A alternating e.m.f. e = 200 sin (100 pit) is connected across a resistor of resistance 10 Omega . Calculate the r.m.s. current flowing through the circuit.

Figure shows a potentiometer with a cell of 2.0 V and internal resistance 0.40 Omega maintaining a potential drop across the resistor wire AB. A standard cell which maintains a constant emf of 1.02V (for very moderate currents upto a few mA) gives a balance point at 67.3 cm length of the wire.To ensure that very low current drawn from the standard cell,a very high resistance of 600 k Omega is put in series with it, which is shorted close to the balance point. The standard cell is then replaced by a cell of unknown emf E and the balance point found similarly,turns out to be at 82.3 cm length of the wire . Would the circuit work well for determining an extremely small emf, say of the order of a few m V (such as the typical emf of a thermo-couple) ? If not , how will you modify the circuit ?
