The current I in an electrical conductor varies inversely as the resistance R of the conductor. The current is 6 amperes when resistance is 940 ohms. What is the current when the resistance is 550 ohms?

V = IR = 6 * 940 = 5640 Volts.
I = V / R = 5640 / 550 = 10.25 Amperes.

OR

I = (940/550) * 6 = 10.25 Amps.
