A potentiometer wire has a length 5m and its resistance of it is connected in series with a resistance of and a cell of emf 2V. The potential gradiant along the wire is :
A potentiometer wire, having a resistance of 5 and length 10 m, is connected in series a cell of emf 5 V and an external resistance of 495 . A potential difference of 1.5 mV will balance against a length of
A load resistance R is connected across a cell of emf E and internal resistance r. If the closed-circuit p.d. across the terminals of the cell is V, the internal resistance of the cell is
The open-circuit potential difference across the terminals of a cell balances on 150 cm of a potentiometer wire. When the cell is shunted by a 4.9 resistor, the balancing length reduces to 147 cm. The internal resistance of the cell is
