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 90 milliamperes when the resistance is 4 ohms, find the current when the resistance is 12 ohms.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 420 milliamperes when the resistance is 2 ohms, find the current when the resistance is 14 ohms.
