Question

Voltmeters V1 and V2 are placed in series and then connected to an ideal battery. V1 reads 80 V and has
resistance 20 kΩ and V2 has resistance 10 kΩ . The EMF of the battery is

Answer 1

TRICK

Since it is a series connection, current  through v1 and  v2 are same

From the given data ,

                 I =80 / 20 k = 4 mA

For the second volt meter the reading is

                 V2 = 4 m x 10 k = 40 V

There fore the net voltage  = 80 +40 = 120 V

                            Hope you understand
