Charge Sharing & Loss of Energy

A 2μ\muF capacitor C1 is first charged to a potential difference of 10V using a battery. Then the battery is removed and the capacitor is connected to an uncharged capacitor C2 of 8 μ\muF. The charge in C2 on equilibrium condition is ____________ μ\muC. (Round off to the Nearest Integer)

Numerical answer type. Work it out, then open the answer.

Show answer and solution

Answer: 16

  1. Q=2×10=20 μQ = 2 \times 10 = 20\ \muC
  2. Common potential V=202+8=2V = \frac{20}{2 + 8} = 2 V
  3. q2=8×2=16 μq_2 = 8 \times 2 = 16\ \muC
