When an electric lamp is connected to 12V battery, it draws a current 0.5A. Find the power of the lamp.
Question
Solution 1
The power P of an electrical device is given by the formula P = IV, where I is the current and V is the voltage.
In this case, the voltage V is 12V and the current I is 0.5A.
Substituting these values into the formula gives:
P = 0.5A * 12V = 6W
So, the power of the lamp is 6 Watts. Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study problem. Knowe
