The correct option is 110 W.
Explanation
Electric power ($P$) represents the rate at which electrical energy is consumed or dissipated into other forms of energy, such as heat or light, in an electric circuit. It is quantitatively defined as the product of the potential difference ($V$) across the device and the current ($I$) flowing through it.
Calculation
To determine the power consumed, the following relationship is used:
$P = V \times I$
Given the values in the question:
- Voltage ($V$): 220 V
- Current ($I$): 0.50 A
Substituting these values into the formula:
$P = 220 \times 0.50$
$P = 110 \text{ W}$
Therefore, the power consumed by the device is 110 Watts.
Key Takeaway: The electric power consumed by a device is directly proportional to both the voltage applied across it and the current flowing through it, expressed by the formula $P = VI$. The SI unit of power is the Watt (W).
