In an electrical circuit, the voltage across a resistor is directly proportional to the current (amps) running through the resistor. If a current of 12 amps produced 480 amps volts across a resistor, how many volts would a current of 1.5amps produce across an identical resistor?
Accepted Solution
A:
since it's the same resistor so R is constant R = V/I =480/12=40 when I = 1.5 , V/1.5 =40 , V = 1.5 x 40 = 60 v
