Why should the resistance of a voltmeter be very high?
MEDIUM

IMPORTANT
You are provided with one low resistance RL and one high resistance RH and two galvanometers. One galvanometer is to be converted to an ammeter and the other to a voltmeter. Show how you will do this with the help of simple labelled diagrams.
