      To calculate the value of the capacitor (C) required for the commutating circuit in a voltage commutated chopper feeding power to an electric car, we can use the formula related to the energy storage in a capacitor and the turn-off time of the SCR.

      The required formula is:

      [ C = frac{I cdot t}{V} ]

      Where:

      – ( I ) = load current (in Amperes)

      – ( t ) = turn-off time of the SCR (in seconds)

      – ( V ) = voltage across the capacitor (in Volts)

      Given:

      – Battery voltage ( V = 60 , V )

      – SCR turn-off time ( t = 20 , mu s = 20 times 10^{-6} , s )

      However, to complete this calculation, we need the load current ( I ). If you provide me with that value, I can help you find the required capacitance ( C ).

      Without the value of load current, I cannot provide a numerical answer. Thus, please provide the load current for a complete calculation. If it’s not available, the answer would be:
