In the circuit shown, an ideal cell of emf E is connected in series to a non-ideal ammeter and voltmeter. Reading of the voltmeter is V0. When a resistance is added in parallel to the voltmeter its reading becomes V0/10 and the reading of the ammeter becomes 10 times the earlier value. find V0 In [...]

In the figure shown PQ is a potentiometer wire. When galvanometer is connected at A, it shows zero deflection when PJ=x. Now the galvanometer is connected to B and it shows zero deflection when PJ=3x. find the value of unknown resistance RX in term of R. In the figure shown PQ is a potentiometer wire. [...]
