If the voltage V, in an electric circuit is held constant,the current,I,is inversely proportional to the resistance,R. If the current is 490 milliamperes when the resistance is 5 ohms,find the current when the resistance is 35 ohms.

1 answer

I = 490 mA = 0.49A.

V = IR = 0.49 * 5 = 2.45V

I = V / R = 2.45 / 35 = 0.07A = 70 mA.
