Question

What is the power consumed by an electrical device that uses 2 A current at 220 V?

• A. 110 W
• B. 220 W
• C. 440 W
• D. 880 W

Hint:

Power = Voltage × Current. Use correct units (Volts and Amperes) to get power in Watts.

Answer 1

The Correct Option is C

To determine the power consumed by an electrical device, we use the formula for electric power:

P = I × V

where:

• P is the power in watts (W)
• I is the current in amperes (A)
• V is the voltage in volts (V)

Given values are:

• Current, I = 2 A
• Voltage, V = 220 V

Substitute these values into the power formula:

P = 2 A × 220 V

P = 440 W

Thus, the power consumed by the device is 440 W.
