Best Answer: Volts don't go through, amps do. Houses in the US are typically wired for 200 amps. Older houses may have 100 amps. Standard house voltage in the United States is 110-120 for the outlest in most rooms, and 220-240 for the big outles like the dryer, stove, water heater, and large air conditioners. Volts times amps equals watts. Watts are what you pay for. Well, watts over time anyway.
