Answer:
Answer is B
Explanation:
voltmeter is used to measure potential in a circuit. It is placed IN PARALLEL with the circuit.
it's net resistance is high so according to ohm's law less current will flow through it and we can measure the potential easily!

Answer:
❤. B is the correct answer here.
As the resistance of voltmeter is too high, so it draws negligible current from the circuit ,hence potential drop in the external circuit is also negligible.
