In this problem, we are dealing with power in circuits. Thus, we'll need the relation:
Power in circuits:
The potential across each resistor and the current in the circuit are unknown. Thus, we'll need more relations:
Lastly, we need the circuit resistance. The given resistors are in series.
How much power is dissipated by each resistor in the figure below, in which V = 9 V and R2 = 15 Ω?
