I am working on creating a game in which players build a circuit, but there
is a gap in my understanding of all of the math. It is difficult to find
this "formula" because there are so many measuring systems. Let's say the
interaction is that the players of my game place the virtual batteries and
use resistors in the circuit to dampen the current. For example, how do
current and voltage both convert to watts? To illustrate, let's say I
wanted to deliver 30 watts of elect.to light a lamp. Let's say the current
coming from some batteries is shown to be 40 amps. Each resistor (say we
use two) resists 5 volts. Is this correct?
