The correct answer is both inductive and capacitive loads because these types of loads introduce reactive power components in an electrical circuit.

Inductive loads, such as motors, transformers, and coils, store energy in a magnetic field when current flows through them. This results in a phase difference between the voltage and current, where the current lags behind the voltage. The reactive power, which does not perform any actual work but is necessary to maintain the magnetic fields, is essential for the proper functioning of these devices.

On the other hand, capacitive loads, like capacitors and certain types of lighting equipment, store energy in an electric field. In this case, the current leads the voltage, again creating a phase difference. Capacitive loads also contribute to reactive power, but in the opposite direction compared to inductive loads.

Both of these processes are integral to alternating current (AC) circuits, which is why they are both responsible for introducing a reactive power component. This reactive power is crucial in power systems for voltage regulation and improving the efficiency of electrical networks.
