A parallel plate air capacitor is charged to a potential difference of V volts. After disconnecting the charging battery the distance between the plates of the capacitor is increased using an insulating handle. As a result the potential difference between the plates:

Options

  1. Aincreases
  2. Bdecreases
  3. Cdoes not change
  4. Dbecomes zero

Correct answer

A. increases

Step-by-step solution

According to the question = Const and decrease in C means increase in V . aligned & C= t o f d & Capacitance = Charge Potential difference & Potential difference & = Charge Capacitance . & aligned
