Question 538917: The current I in an electrical conductor varies inversely as the resistance R of the conductor. If the current is 0.5 amperes when the resistance is 240 ohms, what is the current when the resistance is 960 ohms?

You could start with Ohm's law:
E+=+I%2AR Solve for I.
I+=+E%2FR Substitute I = 0.5 amps. and R = 240 ohms.
0.5+=+E%2F240 Solve for E.
E+=+0.5%28240%29
E+=+120 Now Ohm's law looks like:
I+=+120%2FR Substitute R = 960 ohms.
I+=+120%2F960 Evaluate.
I+=+0.125 amperes.
