When two 25 watt, 120 volt lamps are connected in parallel to a 120 volt source, what is the total power consumed by the lamps?

When two identical 25 watt lamps are connected in parallel to a 120 volt source, the total power consumed is the sum of the power consumed by each lamp. In a parallel circuit, each lamp operates independently at the same voltage, which means each lamp will draw its rated power.

Since each lamp is rated at 25 watts, when both lamps are connected in parallel, the total power consumption can be calculated by adding the power of the two lamps together:

Power of lamp 1 + Power of lamp 2 = 25 watts + 25 watts = 50 watts.

Therefore, the total power consumed by the lamps is 50 watts. This reflects the nature of parallel circuits where the voltage remains constant across all components, allowing for additive power consumption.
