A potential difference of 100 V produces a current of 3.0 A in a certain resistor. (a) What is the resistance of the resistor? (b) What is the current when the potential difference is 25 V?
Please show work.
Homework Answers
a) By Ohm's law
V = IR
R = V/I = 100 / 3 = 33.33 ohm
b) I = V/R
= 25 / 33.33
= 0.75 A
