Question 10

A student wants to determine the resistance of a filament lamp LLL. They set up a circuit containing a DC power supply, a variable resistor (rheostat), an ammeter, and a voltmeter.

Which of the following descriptions represents the correct circuit configuration?

A

The ammeter is connected in parallel across the lamp LLL, and the voltmeter is connected in series with the variable resistor.

B

The ammeter is connected in series with the power supply, variable resistor, and lamp LLL, and the voltmeter is connected in parallel across the lamp LLL.

C

The ammeter is connected in series with the power supply and the variable resistor, and the voltmeter is connected in parallel across the combination of both the variable resistor and the lamp LLL.

D

The voltmeter is connected in series with the lamp LLL, and the ammeter is connected in parallel across the lamp LLL.
