Question

1.)A circuit has a current of 0.5A and a resistence of 8 ohms. What is the resistence? 2.) A circuit has a voltage of 9V and a current of 3A, what is the resistence?

Answer 1

1. are you serious asking the resistance? it's 8 Ohms. if you ask the voltages the result is

v = i . r

v = 0.5 . 8 = 4V

2. r = V/i = 9/3 = 2 ohm
