Concept

Problem: How much power is dissipated by each resistor in the figure below, in which V = 9 V and R2 = 15 Ω?

FREE Expert Solution

In this problem, we are dealing with power in circuits. Thus, we'll need the relation:

Power in circuits:

P=Vi=i2R=V2R

The potential across each resistor and the current in the circuit are unknown. Thus, we'll need more relations:

Ohm's law:

i=VR

Lastly, we need the circuit resistance. The given resistors are in series.

Equivalent resistance:
