A diode works in _ bias for first cycle of rectification.
Correct answer: A. Forward
- A. Forward
- B. Reverse
- C. Mid
- D. Positive
Explanation
Correct option is A. A diode works in forward bias for rectification. Rectification is the process of converting alternating current (AC) to direct current (DC). A diode is a semiconductor device that allows current to flow in one direction only. When a diode is forward biased, the current flows easily through the diode. When a diode is reverse biased, the current does not flow through the diode. In a rectifier circuit, the diode is used to allow current to flow in one direction only. This is done by applying a forward bias to the diode during the positive half-cycle of the AC input signal. The diode will then conduct current, and the output of the rectifier circuit will be a DC signal.

About Alternating Current
Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
