55. ssm Two resistors, 42.0 and 64.0 Ω, are connected in parallel. The current through the 64.0-Ω resistor is 3.00 A. (a) Determine the current in the other resistor. (b) What is the total power supplied to the two resistors?

Since the two resistors are in parallel, they must have the same voltage across them, so the voltage across them is found from

The current in the other resistor is now found from

Now we find the power for the 64 Ω resistor we use current and resistance as follows

For the 42 Ω resistor we can do the same

So total Power is
