Two resistors, 34.8 and 84.1Ω, are connected in parallel. The current through the 84.1-Ω resistor is 2.47A. (a) Determine the current in the other resistor. (b) What is the total power supplied to the two resistors?
Recall that I = E/R
E is the same across both resistors, if they are in parallel. So,
34.8*I = 84.1*2.47
Now you have I for both resistors, and the power in each is I^2*R
