Ohm's law states that V = IR for a simple circuit, where V is the total voltage, I is the amount of current running through the resistor and R is the resistance of the resistor. If I = 40 amperes when R = 3 ohms, find the amount of current (in amperes) when the resistor has a resistance of 20 ohms. Assume voltage remains constant.

V = 40*3 = 120
For our second equation V=IR --> 120=I*20 --> I = 6 amperes
