Problema Solution

Electrical Current: The current I in an electrical conductor varies inversely as the resistance R of the conductor. The current is 1/3 amperes when the resistance is 1620 ohms. What is the current when the resistance is 4500 ohms?

Answer provided by our tutors

by using Ohm's law


Voltage = Current * Resistance


V = I * R


1) V = 0.333 * 2268 = 755 volt


2) I = V / R


I = 755 / 12348 = 0.061 A


= 61 mA
