Given the voltage of the lamp and the amount of current use, the power used by the lamp is 60Watts.

What is the power used by the lamp?

Power is the quantity of energy transferred per unit time. It can be expressed as;

P = v × I

Where v is voltage and I is current.

Given that;

  • Voltage v = 120V
  • Current I = 0.5A
  • Power P = ?

P = v × I

P = 120V × 0.5A

P = 60Watts

Therefore, given the voltage of the lamp and the amount of current use, the power used by the lamp is 60Watts.
