What happens to the brightness of light emitted by a light bulb when the current in it increases?
To Explain: Effect on brightness of light emitted by a bulb when current increases.
Answer to Problem 40A
Brightness increases.
Explanation of Solution
Introduction:
A bulb glows when current is passed through it. A light bulb contains a heating element which heats up and glows when current is passed through it.
The brightness of the bulb depends on the amount of current flowing through it. When the current is increased, the brightness would also increase.
Conclusion:
Brightness of light emitted by the bulb increases when current increases.
