Which component is responsible for delivering energy to the AC load?

• A. Primary Coil
• B. Secondary Coil
• C. Transformer
• D. Resistor

Answer: (B)

The secondary coil is responsible for delivering energy to the AC load because it is specifically designed to receive energy transferred from the primary coil through electromagnetic induction in a transformer. When alternating current flows through the primary coil, it creates a magnetic field that induces a current in the secondary coil. This induced current is what provides the energy necessary for the AC load connected to the secondary side.

In a transformer, the primary coil receives input electrical energy, but it is the secondary coil that ultimately delivers this energy to a load, allowing for the voltage to be transformed and utilized appropriately based on the needs of the circuit.
