Explanation:
The power factor is defined as the ratio of the real power to the apparent power of an AC circuit. It is a measure of the efficiency of the circuit in converting the electrical power into useful work.
Incandescent bulbs are the simplest form of electric lighting and consist of a tungsten filament that is heated by an electric current until it glows. These bulbs have a resistive load and draw a current that is in phase with the voltage, which means that the power factor is unity.
The power factor of an incandescent bulb is unity because:
• Incandescent bulbs have a resistive load, which means that the current flowing through them is in phase with the voltage.
• The real power consumed by the bulb is equal to the apparent power, as there is no reactive power component.
• The power factor is therefore equal to 1, which is the maximum possible value.
In summary, the power factor of an incandescent bulb is unity because it has a resistive load, and there is no reactive power component.
