Depending on whether you have an electrical dryer or a gas dryer, the answer will be different. I am going to assume you are in the US, and using an electrical dryer. Then the calculation goes like this:

Assuming you have an electrical dryer, typical power use might be anywhere from 1800 W to 5000 W source. But let's assume the dryer you have is right at the limit of your electrical circuit - that is a 30 A, 240 V dedicated circuit. I will compute the voltage and power drop resulting from using different gages of wire, assuming that current (which is high... more likely the current is somewhere between 8 or 22 A).

Resistance of 220 (round trip!) feet of wire source and associated voltage drop and power loss (assuming 30 A current):

AWG Ohms Drop(V) Power loss 6 0.087 2.61 2.2% 8 0.138 4.14 3.5% 10 0.220 6.60 5.5% 12 0.349 10.47 8.7%The voltage drop you will get is current times resistance (V = I x R), for example 30 x...
