    A half-wave rectifier employs a transformer with turn ratio n1 : n2= 1...
    The turn ratio of transform ation is 12:1. So if primary coil is connected to power mains o f 220V , then potential of secondary coil is Volts. In a half-wave rectifier,is the maximum voltage appearing across the transformer secondary coil. Now. peak inverse voltage, for half wave rectifier in given as V0

    = 25.9V
    The correct answer is: 25 .9

    A half-wave rectifier employs a transformer with turn ratio n1 : n2= 1...
    Given information:
    - Transformer turn ratio: n1 : n2 = 12 : 1
    - Input voltage: 220V, 50Hz
    - Diode resistance in forward bias: negligible

    Calculating peak voltage:
    The peak voltage of the input signal can be calculated using the formula:

    Vp = Vm × √2

    Where Vp is the peak voltage and Vm is the maximum voltage.

    The maximum voltage can be calculated using the formula:

    Vm = Vrms × √2

    Where Vrms is the root mean square (RMS) voltage.

    The RMS voltage can be calculated using the formula:

    Vrms = Vdc / √2

    Where Vdc is the DC voltage.

    Calculating DC voltage:
    The DC voltage can be calculated by multiplying the peak voltage of the input signal by the duty cycle.

    In a half-wave rectifier, the duty cycle is 0.5 since only half of the input waveform is rectified.

    Therefore, the DC voltage is given by:

    Vdc = Vp × 0.5

    Calculating peak inverse voltage (PIV):
    The PIV is the maximum voltage that appears across the diode when it is in reverse bias.

    In a half-wave rectifier, the PIV is equal to the peak voltage of the input signal.

    Calculating the turn ratio:
    The turn ratio of the transformer is given as n1 : n2 = 12 : 1.

    This means that for every 12 turns on the primary coil, there is 1 turn on the secondary coil.

    Calculating the secondary voltage:
    The secondary voltage can be calculated using the turn ratio formula:

    V2 / V1 = n2 / n1

    Where V2 is the secondary voltage and V1 is the primary voltage.

    In this case, V1 is the input voltage of 220V.

    Plugging in the values, we get:

    V2 / 220 = 1 / 12

    Cross-multiplying, we get:

    V2 = 220 / 12 = 18.33V

    Calculating the peak voltage:
    The peak voltage of the secondary voltage can be calculated using the formula:

    Vp2 = V2 × √2

    Plugging in the value of V2, we get:

    Vp2 = 18.33 × √2 = 25.9V

    Therefore, the peak inverse voltage (PIV) of the diode is approximately 25.9V.
