A capacitor of capacitance C is connected to two voltmeters A and B . A is an ideal voltmeter having infinite resistance, while B has resistance R . The capacitor is uncharged and then the switch S is closed at t =0 ,

Options

  1. AReadings of B and A will be and zero at t=0
  2. BDuring time interval (0 t ) readings of B and A are changing
  3. CReading of A and B will be equal at t = RC 2
  4. DNone of these

Correct answer

C. Reading of A and B will be equal at t = RC 2

Step-by-step solution

Potential across A & B should same. V ₀ 2 = V ₀ (1- e ^ - t RC )
