    Answer: 1.176*10^-3 s

    Explanation: The time constant formulae for an RC circuit is given below as

    t = RC

    Where t = time constant, R = magnitude of resistance = 21 ohms, C = capacitance of capacitor = 56 uf = 56*10^-6 F

    t = 56*10^-6 * 21

    t = 1176*10^-6

    t = 1.176*10^-3 s
