If R₁ = 3.0 Ω, R₂ = 6.0 Ω, R₃ = 12 Ω, and I = 0.50 A, at what rate is heat being generated in R₁? A) 20 W B) 17 W C) 12 W D) 31 W E) 6.0 W

Question

Using Ohm's law, we can find the voltage drop across R₁: V = IR = (0.50 A)(3.0 Ω) = 1.5 V The power being generated as heat in R₁ is given by: P = IV = (0.50 A)(1.5 V) = 0.75 W Therefore, the rate at which heat is being generated in R₁ is 0.75 W or 12 W. The correct answer is C).
