Question

If more current flows in a circuit, what happens to the new bulb in terms of wattage and brightness?

a) Consumes less wattage and dims
b) Consumes more wattage and is brighter
c) No change in wattage or brightness
d) Causes a short circuit

Answer 1

When more current flows in a circuit, the new bulb will consume more wattage and be brighter.

Step-by-step explanation:

When more current flows in a circuit, the new bulb will consume more wattage and be brighter. This is because power in an electric circuit is calculated using the formula P = IV, where P is power, I is current, and V is voltage. If the current increases, the power consumed by the bulb will also increase, resulting in a brighter light. Additionally, the brightness of a light bulb is directly proportional to the power consumed by the bulb.

For example, let's consider two light bulbs operating at the same voltage. If one bulb has a power rating of 25 watts and the other has a power rating of 60 watts, the 60-watt bulb will draw more current and be brighter than the 25-watt bulb.
