An electric bulb is connected to a 110 V generator. The current is 0.2 A. What is the power of the bulb ?

The power of an electrical device is defined as the rate at which electrical energy is consumed or work is performed in a unit of time. For a purely resistive device like an electric bulb, the power consumption (P) is calculated using the fundamental formula P = V × I, where V represents the potential difference in volts and I represents the current in amperes. In this specific problem, the electric bulb is connected to a generator providing a voltage (V) of 110 V and draws a current (I) of 0.2 A. By substituting these values into the formula, we get P = 110 V × 0.2 A, which equals 22 Watts. This relationship between voltage, current, and wattage is a core principle of electricity used to determine the power rating of various household appliances.
