Question

If an AC voltage of rms value of 10 volts is applied as input of a half-wave rectifier, then the voltage value of the DC output will be:

Options
  • A

    10 V

  • B

    10.3 V

  • C

    10.7 V

  • D

    9.3 V

Explanation

Since we have the voltage at AC input, which is 10 V, we just need to subtract this value by the diode drop, which is 0.7 V;

10 – 0.7 = 9.3V 

This option is incorrect. 

Since we have the voltage at AC input, which is 10 V, we just need to subtract this value by the diode drop, which is 0.7 V;

10 – 0.7 = 9.3V

This option is incorrect. 

Since we have the voltage at AC input, which is 10 V, we just need to subtract this value by the diode drop, which is 0.7 V;

10 – 0.7 = 9.3V

This option is incorrect.

Since we have the voltage at AC input, which is 10 V, we just need to subtract this value by the diode drop, which is 0.7 V;

10 – 0.7 = 9.3V

This option is correct one.

Since we have the voltage at AC input, which is 10 V, we just need to subtract this value by the diode drop, which is 0.7 V;

10 – 0.7 = 9.3V
