Question 222Electricity & Electronics - QMED

The correct answer is C) 200 watts. When two 100 watt light bulbs rated at 100 volts are connected in parallel across a 100 volt power supply, the total power consumed by the two bulbs is equal to the sum of the power consumed by each individual bulb. Since each bulb is rated for 100 watts at 100 volts, the power consumed by each bulb is 100 watts. With two bulbs connected in parallel, the total power consumed is 100 watts + 100 watts = 200 watts. The other options are incorrect because: A) 50 watts is only half the total power consumed. B) 100 watts is the power consumed by a single bulb, not the total for both. D) The product of amperes and voltage in each branch does not directly give the total power consumed.
