Power Consumption in an AC Circuit
Power consumption in an AC circuit occurs in the component that dissipates energy in the form of heat. In an AC circuit, power is consumed only in the resistance.

Resistance
- In a resistor, the energy is dissipated in the form of heat due to the resistance offered by the material to the flow of current.
- The voltage drop across a resistor causes a current to flow through it, resulting in the generation of heat.

Capacitor and Inductor
- Capacitors and inductors are reactive components in an AC circuit and do not dissipate power in the form of heat.
- In a capacitor, energy is stored in an electric field and then released back to the circuit without any loss.
- In an inductor, energy is stored in a magnetic field and returned to the circuit without any loss.

Choke
- A choke is an inductor used to block high-frequency alternating current while allowing low-frequency or direct current to pass.
- Chokes do not consume power in an AC circuit but rather regulate the flow of current.
In conclusion, power is consumed only in the resistance in an AC circuit due to the conversion of electrical energy into heat. Capacitors, inductors, and chokes do not dissipate power but play other vital roles in the circuit.
