Question #73952

1. A two-metre potentiometer wire is used in an experiment to determine the internal resistance of a voltaic cell. The e.m.f of the cell is balanced by the fall of potential along 90.6cm of wire. When a standard resistor of 10 0hms is connected across the cell the balance length is found to be 75.5cm . Draw a labelled circuit diagram and

calculate from first principles, the internal resistance of the cell.

2. A 2UF capcitor charged originally to a potential difference of 60v is

discharged across a 22mΩ resistor as shown in the figure. Calcualte

the time constant of the ccircuit and the potential differnce across the

capacitor after this time constant time?

3. Find the current in every branch of the two loop circuit.
