Chapter 35, Problem 35A

As more and more lamps are connected in series to a flashlight battery, what happens to the brightness of each lamp?

To determine

The effect on the brightness of each lamp due to the connection of more and more lamps in the series with a flashlight battery.

Explanation of Solution

Introduction:

The brightness of each lamp depends on the easier flow of current or more current through each lamp. The flow of current becomes easy if the resistance in the path of the electron becomes less.

When more and more lamps are connected in series, the equivalent resistance of the lamps increases. The current through each lamp reduces due to increased equivalent resistance of the lamps and results in the brightness of each lamp to be dimmer.

Conclusion:

The brightness of each lamp dimmers due to the connection of more and more lamps in the series connection.
