In a celebration of an event, a 500 W bulb operates at 220 V and has a periodic fluctuation of 2 s. The electric current passing through the bulb is
Correct answer: B. 2.27 A.
- A. 0.44 A.
- B. 2.27 A.
- C. 5.44 A.
- D. 7.27 A.
Explanation
The correct answer is Option B: 2.27 A. To find the electric current passing through the bulb, we use the formula: Current (I) = Power (P) / Voltage (V). Substituting the given values, Current = 500 W / 220 V = 2.27 A. The other options are incorrect as they do not correctly calculate the current based on the power and voltage values provided.

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.
