PARAGRAPH: Experiments with a charged capacitor: A capacitor and a Pendulum: We begin with an uncharged, isolated, parallel plate capacitor having its plates maintained at a fixed distance apart and with an isolated independent voltage source. By connecting the two plates of the uncharged capacitor momentarily to the independent voltage source and then disconnecting the source, we are left with a charged and isolated

Options

  1. Athe current is from left to right
  2. Bthe current is from right to left
  3. Cthe current is from left to right during when ball moves to the left and the current is from right to left whe
  4. Dthe current is from right to left during when ball moves to the left and the current is from left to right whe

Correct answer

A. the current is from left to right

Step-by-step solution

aligned & U _ q + U _ R = U ₀= 1 2 Q ^2 C & U _ C = U _ R & U _ L = U ₀ 2 = 1 2 Q ^2 C aligned
