A 1000 W lamp operates at 220 V for 60 s.The electric current passing through the lamp will be
Correct answer: A. 1.66 A
- A. 1.66 A
- B. 3.57 A
- C. 4.54 A
- D. 6.25 A
Explanation
The power formula is given by P = VI, where P is the power in watts, V is the voltage in volts, and I is the current in amperes.Rearranging the formula to solve for current gives I = P/V. Substituting the given values, I = 1000 W / 220 V = 4.54 A. However, this was a miscalculation. The correct calculation should be I = 1000 W / 220 V = 4.54 A. Note that the correct calculation would actually give I = 4.54 A, but there seems to be a confusion here. The correct calculation should be I = 4.54 A, indicating an error in the problem statement or expected answer.Re-evaluate the problem setup as necessary for consistency.

About Steady Current
Steady current is the continuous flow of charge at a constant rate through a conductor. The topic covers current, charge, potential difference, resistance, Ohm's law, resistivity and electrical power, along with series and parallel circuits, while distinguishing conventional current direction from electron motion.
