A certain thermocouple (treat it as a seat of e.m.f) which has a total resistance of `10Omega` has one junction in melting ice and the other junction in melting ice and the other junction is steam. The e.m.f. between its ends as measured with a potentiometer is 4 millivolt. What would be its reading when it is connected to a milli volt meter which has a resistance of 50 ohm?
