And electricians out there

So if I used the bigger heat bulb like 250 watt you are saying it uses less voltage or current?
I took a course in "farm electrification" 40 years ago but it was too much like math which I hate!!!

No, 250W divided by 120 Volts is just over 2 amps.

The equation is Watts/Volts=Amps

If the Voltage was 240, it would be 125W/240V=0.52A
