Two capacitors C₁ and C₂ are connected separately across the same battery. Their charge-versus-time curves in the original figure show final charge Q₂>Q₁. If stored energies are U₁ and U₂, which is correct?

Question

G1 Physics · Accepted Answer

At steady state both have the same voltage V. Since Q=CV and Q₂>Q₁, C₂>C₁. Also U=(1/2)CV², so U₂>U₁. Therefore C₁
