Q17 / 88 · NTA Abhyas (JEE Main) 2020 · Physics · Semiconductors

An ideal diode is connected in a circuit with resistance R=50 Ω and V=10 V. If an AC input signal shown in the figure is given to the circuit, then the maximum and minimum value of output voltage (without load) is
Figure

  • A
    10 V,-15 V
  • Correct answer
    B
    10 V,-25 V
  • C
    25 V,-25 V
  • D
    25 V,-15 V

Solution

For the positive half cycle, the diode is in reverse bias. Due to this there will be no current in the resistor, hence the output voltage

Voutput=10 V

For the negative half cycle,

the potential difference across output =-25 V

Hence, the correct answer is option: 'B'.
