Answer Posted / nitin pulastya
I disagreed with "Magbool", He is talking "in case of open circuit,voltage is equal to emf of cell but current is equal to zero" only for an ideal condition but in practically this is not possible, Bcz a little amount of current goes in the Voltmeter circuit. To prove my statement:
If there is a current then definitely there will be a voltage across the medium (resistance). Its OK the input impedance of voltmeter is much high but practically not infinite, therefore some current will go inside the voltmeter.
