Question 23

To determine the electrical resistance of a resistor, a student connects both an ammeter and a voltmeter to the resistor in a circuit. Which of the following correctly describes how these meters are connected relative to the resistor, and what their ideal internal resistances should be?

A

Ammeter in parallel with very high resistance; voltmeter in series with very low resistance.

B

Ammeter in series with very high resistance; voltmeter in parallel with very low resistance.

C

Ammeter in parallel with very low resistance; voltmeter in series with very high resistance.

D

Ammeter in series with very low resistance; voltmeter in parallel with very high resistance.
