Question

In a series connection, you have a battery, a 10 Ohm resistor, a light bulb, and then a 15 Ohm resistor, in that order. Which of the following is/are true? More than one answer may be correct.

The light bulb would become dimmer if the resistance in the circuit increased.

The current through the light bulb and that through each resistor is equal.

If you reconfigured the order of the components in the circuit, you could increase the current in the light bulb.

The light bulb would become brighter if the resistance in the circuit increased.

The current through the light bulb is less than that passing through the resistors.

2)Consider the circuit shown below. At which switch setting will the bulb B be the brightest?

Switch S1closed, switch S2closed, and switch S3/closed.Switch S1open, switch S2closed, and switch S3/open.Switch S1closed, switch S2closed, and switch S3open.Switch S1open, switch S2closed, and switch S3/closed.

Explanation / Answer

The light bulb would become dimmer if the resistance in the circuit increased. The current through the light bulb and that through each resistor is equal. 2) broken image
