Question

Capacitors C₁=1 μF and C₂=2 μF are separately charged from the same battery and then discharged separately through equal resistors. Which statements are correct?

G1 Physics · Accepted Answer

Both start with the same voltage V and equal discharge resistance, so I(0)=V/R is equal and non-zero. Their time constants are RC; C₁ has the smaller τ, so it reaches 50% charge sooner. Correct: B, D.
