Mutual inductance is the principle of:

• A. Converter
• B. Inverter
• C. Transformer
• D. Rectifier

Mutual inductance refers to the phenomenon where a change in current in one coil induces a voltage in another nearby coil. This principle is fundamental in the operation of devices that transfer electrical energy between coils.

Key Concepts

• Converter: Converts one form of electrical energy to another.
• Inverter: Changes direct current (DC) to alternating current (AC).
• Transformer: Utilizes mutual inductance to transfer electrical energy between circuits at different voltage levels.
• Rectifier: Converts AC to DC.

Correct Answer

The correct choice is C. Transformer. Transformers rely on mutual inductance to function effectively, making them essential in power distribution systems.
