A 100 amp service will supply your electrical current needs UP TO 100 amps.
When doing load calculations on a 100 amp panel it can only be loaded up to 80 amps.

In a 200 amp service, each leg carries 100 amps. However, since the legs are 180 degrees out of phase, you can achieve 240 volts across both legs. So, a 200 amp service typically consists of two 120 volt legs, each providing up to 100 amps.
The formula you are looking for is W = E x I. Watts = Volts x Amps.
You need the volts times the amps to equal 100 Watts. On 12 v that is 8.33 amps, or on 200 v is it 0.5 amps.
100 amps
To supply 100 amps from 1.5 volts, you would need to use a very low resistance load. Using Ohm's Law (V = I*R), you can calculate that in order to achieve 100 amps with 1.5 volts, the load resistance would need to be approximately 0.015 ohms. Such low resistance loads can be challenging to find and may not be practical for most applications.
