Question

How must a secondary circuit of the inductor in a full wave rectifier be grounded?

1. The secondary circuit of the inductor in a full wave rectifier must be grounded to the chassis of the power supply.
2. The secondary circuit of the inductor in a full wave rectifier must be grounded to the neutral conductor of the AC power source.
3. The secondary circuit of the inductor in a full wave rectifier must be grounded to the earth ground.
4. The secondary circuit of the inductor in a full wave rectifier does not need to be grounded.

Answer 1

The correct option is 3. The secondary circuit of the inductor in a full wave rectifier must be grounded to the earth ground to ensure safety and prevent electrical shocks.

Step-by-step explanation:

The secondary circuit of the inductor in a full-wave rectifier is typically involved in the process of converting alternating current (AC) into direct current (DC). For safety purposes and to maintain the case voltage near zero, grounding is often employed. When it comes to grounding the secondary circuit of the inductor, the most common practice is to ground it to the earth. This ensures any leakage current due to electromagnetic induction is safely directed away, reducing the risk of electric shock.

It is important to follow local electrical codes and regulations, which usually dictate the proper grounding method. Often, the secondary is connected to the rectifier and the entire assembly is grounded to the earth to maintain the safety and proper functioning of the equipment.
