Question

Two resistors of resistance 100 Ω and 200 Ω are connected in parallel in an electrical circuit. The ratio of the thermal energy developed in 100 Ω to that in 200 Ω in a given time is:

G1 Physics · Accepted Answer

Step 1: Parallel resistors have same voltage V. Step 2: Heat dissipated H = (V²/R)t. Step 3: H₁₀₀/H₂₀₀ = R₂₀₀/R₁₀₀ = 200/100 = 2:1.
