Question

You connect a voltmeter to an unknown resistor in a circuit in order to measure the potential difference across that resistor. How should you connect it to the resistor and what would the voltmeter's ideal internal resistance be? A. In series Fint B. In parallel; int- O C. In series; rint- 0 D. In parallel; rint →

Answer 1

Answer:

option (a)

Explanation:

To make a galvanometer into voltmeter, we have to connect a high resistance in series combination.

The voltmeter is connected in parallel combination with teh resistor to find the voltage drop across it.

An ideal voltmeter has very high resistance that means it has a resistance as infinity.

Answer 2

Answer:

A. In series Fint

Explanation:

If you connect it to the resistor, the voltmeter's ideal internal resistance be  In series Fint.
