Answer:

A. In series Fint

Step-by-step explanation:

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

Answer:

option (a)

Step-by-step 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.
