How many electrical circuits? [closed]


Wire design is usually based on minimizing the length of wire needed. By putting all lights on one circuit and outlets on another, it would require more wire than would normally be used and also cause needless inconvenience if the light circuit tripped late at night.

Also note that some range hoods require a dedicated circuit. Also, unless the range hood is 240 volts (which would be unusual in the U.S.) it should not share a circuit with a 240 volt range.

Another minor point is that having each room on a separate dedicated circuit means that if that circuit is off, everything in the room is off thus making a simple repair into one which requires an extension cord from another room or a battery powered device.

Unless you know otherwise, heating and air conditioning are not operated simultaneously, so it is generally okay to combine those on the same circuit. However, if the heat is 120 volts (like a gas furnace) and the a/c is 240 v (or vice versa), then they...

You'll have to start from the basics: Ohm's and Kirchoff's laws.

You'll have to look at hundreds or thousands of circuits and analyze their behavior. It's impossible to design a circuit if you have never analyzed any and have no idea of how to achieve your desired functionality.

Electronics is an art as well as a science. You have to make a lot of mistakes before you will gain sufficient intuition to design circuits. I've been doing this for years, and I still constantly make mistakes. (I didn't even type this sentence correctly when I first submitted this post. Electronics design is harder than typing.)

It could take a designer hours to explain why they chose a specific value for one specific component in a subcircuit. It is not feasible to explain how an electronic product is designed in full. It's an iterative process of requirement definition, design, test, and validation of requirements.

If we want to keep a record of how we constructed a specific electric circuit, we can take a photo of it. If we do not have a camera, we can remember the circuit by drawing a sketch.

Look at the sketch below which Farrah drew of the circuit that you made in the activity with the paperclip switch.

That's right Jojo. It takes time to draw a sketch like this one that Farrah drew. It will even take longer if we add more components to a circuit. We could have more than one bulb like in the case of all the lights in your home. There could be also more than one switch. Each light in your home has its own switch.

The easiest way to provide a voltage source for an electronic circuit is to include a battery. There are plenty of other ways to provide voltage, including AC adapters (which you can plug into the wall) and solar cells (which convert sunlight to voltage). However, batteries remain the most practical source of juice for most electronic circuits.

A battery is a device that converts chemical energy into electrical energy in the form of voltage, which in turn can cause current to flow.

A battery works by immersing two plates made of different metals into a special chemical solution called an electrolyte. The metals react with the electrolyte to produce a flow of charges that accumulate on the negative plate, called the anode. The positive plate, called the cathode, is sucked dry of charges. As a result, a voltage is formed between the two plates.

These plates are connected to external terminals to which you can connect a circuit to cause current to...

This KS2 Science quiz will take you on a tour of electrical circuits, looking at how they work and some of their parts - such as batteries, switches and wires.

Electrical circuits are closed paths for currents to flow and they are usually made of components joined by wires. Have you ever counted how many electrical items you have in your house? And would you remember to include those that use batteries? We have become very reliant on electrical goods since the first modern battery was invented by Allesandro Volta in 1800. At the flick of a switch we can have things our ancestors could only have dreamt of!

How much do you know about electrical circuits? Why are electric wires coated with plastic or rubber? What do switches do? What is another name for batteries? Take this quiz to find...

An electrical circuit is a device that uses electricity to perform a task, such as run a vacuum or power a lamp. The circuit is a closed loop formed by a power source, wires, a fuse, a load, and a switch. Electricity flows through the circuit and is delivered to the object it is powering, such as the vacuum motor or lightbulb, after which the electricity is sent back to the original source; this return of electricity enables the circuit to keep the electricity current flowing. Three types of electrical circuits exist: the series circuit, the parallel circuit, and the series-parallel circuit; depending on the circuit type, it may be possible for electricity to continue flowing should a circuit stop working. Two concepts, Ohm's Law and source voltage, can affect the amount of electricity flowing through a circuit, and therefore, how well an electrical circuit functions.

How it Works

Most devices that run on electricity contain an electrical circuit; when connected to a...

Everything is made up of atoms. Each one of them has three particles : protons, neutrons and electrons. Electrons spin around the centre of an atom. They have a negative charge. Protons, which are in the centre of atoms, have a positive charge.

Normally, an atom has as many protons as it has electrons. It is stable or balanced. Carbon, for example has six protons and six electrons.

Scientists can make electrons travel from one atom to another. An atom that loses electrons is positively charged, an atom that gets more electrons is negatively charged.

Electricity is created when electrons move between atoms. Positive atoms look for free negative electrons and attract them, so that they can be balanced.

Conductors and Insulators

Electricity can pass through some objects better than through others. Conductors are materials through which electrons can travel more freely. Copper, aluminium, steel and other metals are good...

A closed circuit has a complete path for current to flow. An open circuit doesn't, which means that it's not functional. If this is your first exposure to circuits, you might think that when a circuit is open, it's like an open door or gate that current can flow through. And when it's closed, it's like a shut door that current can't flow through. Actually, it's just the opposite, so it might take awhile to get used to this concept.

A short circuit is a low-resistance path, usually made unintentionally, that bypasses part of a circuit. This can happen when two bare wires in a circuit touch each other. The part of the circuit bypassed by the short circuit ceases to function, and a large amount of current could start to flow. This can generate a lot of heat in the wires and cause a fire. As a safety measure, fuses and circuit breakers automatically open the circuit when there is an excessive current.

In a series circuit, the same current flows through all the...

Basic Circuits

An electric circuit is an unbroken path along which an electric current exists and/or is able to flow. A simple electrical circuit consists of a power source, two conducting wires (one end of each being attached to each terminal of the cell), and a small lamp to which the free ends of the wires leading from the cell are attached.

When the connections are made properly, the circuit will “close” and current will flow through the circuit and light the lamp.

A simple electrical circuit

Once one of the wires is removed from the power source or a “break” is made in the flow, the circuit is now “open” and the lamp will no longer light.

In practical application, circuits are “opened” by such devices as switches, fuses, and circuit breakers. Two general circuit classifications are series and parallel.

The elements of a series circuit are connected end to end; the same current flows through its parts one after another.
