One ideal cell is used to drive current in a metre bridge circuit. In an experiment x is the balancing length obtained. If we replace the wire of the metre bridge with another wire of material having more rsistivity and lesser diameter, the new balancing length will be

If the current in a primary circuit is I=I_(0) Sin omegat and the mutual inductance is M, then the value of induced voltage in secondary circuit will be :-

Choose the correct statements from the following a) in potentiometer experiment balancing length represent the potential difference across the secondary cell b) the shunt resistance between the terminals of cell in the secondary circuit of potentiometer is increased, the balancing length increases c) in potentiometer experiment the e.m.f of the cell in the secondary circuit may be greater than the e.m.f of cell in the primary circuit d) potentiometer is used to measure thermo e.m.f. also

A student finds the balancing length to be .l. with a cell of constant emf in the secondary circuit. Another student connects the same cell in the secondary circuit of potentio meterof double the length but with a cell of half the emf in the primary circuit. The balancing length will be [cell in primary is ideal and no series resistance is present in primary circuit]
