1. The problem statement, all variables and given/known data Two resistors R1 and R2 are connected in series to a battery supplying a voltage of ∆V as shown. How much power is dissipated by the resistor R2 in the form of heat? Use the following data: R1 = 10 Ω, R2 = 5 Ω, ∆V = 3 V http://tinypic.com/r/153tr91/8 2. Relevant equations Rtotal = R1 + R2 P=V^2/R P= I^2 x R 3. The attempt at a solution Rtot = 10 + 15 = 15 ohms I = 3/15 = .2 A P = (.2^2) x 10 = .4 W Why is this the wrong answer??
