Voltmeters `V_(1)` and `V_(2)` are connected in series across a `D.C.` line `V_(1)` reads 80 volts and has a per volt resistance of `200 ohms`, `V_(2)` has a total resistance of 32 kilo ohms.
The line voltage is

Voltmeters V_1 and V_2 are placed in series and then connected to an ideal battery. V_1 reads 80 V and has resistance 20KOmega and V_2 has resistance 10KOmega . The EMF of the battery is:
