While studying about 'Potentiometer' it's said :
"The resistance of the voltmeter be large compared to the circuit resistance across which the voltmeter is connected.Otherwise an appreciable current will flow through voltmeter which will alter the circuit current & the P.D to be measured". Can anybody explain this concept?.Thanks.
