Question

Why is \[I_q\] called the wattless component?

Options

• Corresponding to this component of current, there is no power loss.

• It increases the resistance until it equals the impedance.

• It is in phase with the voltage and corresponds to power loss.

• It is equal to the peak voltage.

Answer 1

The component \[I_q\] is perpendicular to the applied voltage. It is called wattless because no power loss corresponds to this component.
