In an electrical circuit, the current passing through a conductor varies inversely with the resistance. Suppose that when the current is 2A (amperes), the resistance is 115ohms. What is the resistance when the current is 5A ?

Answer 1

V = I*R = 2 * 115 = 230 Volts = Applied
voltage.

R = V/I = 230/5 = 46 Ohms.
