Physics - Current Electricity Question with Solution | TestHub

The resistances of the four arms $P,Q,R$ and $S$ in a Wheatstone's bridge are $10\Omega ,30\Omega ,30\Omega$ and $90\Omega$, respectively. The emf and internal resistance of the cell are $7\mathrm{V}$ and $5\Omega$ respectively. If the galvanometer resistance is $50\Omega$, the current drawn from the cell will beNEET 2013 (All India)
