Question

A p-n junction (D) shown in the figure can act as a rectifier. An alternating current source (V) is connected in the circuit. The current (I) in the resistor (R) can be shown by

• A. a
• B. b
• C. c
• D. d

Answer 1

The correct option is B b

The given circuit works is half wave rectifier. In this circuit, we will get current through R when p-n junction diode is forward biased and no current when p-n junction is reversed biased. Thus the current through resistance will be shown by graph (b).
