Question
Two batteries A and B are
2.
connected in parallel and load of 10 Qis connected
across their terminals. A has an e.m.f. of 12 V and an
internal resistance of 2 Q ; B has an e.m.f. of 8 V and
an internal resistance of 1 Q Use Kirchhoff's laws to
determine the values and directions of the currents
flowing in each of the batteries and in the external
resistance. Also determine the potential difference
across the external resistance,
Two resistors of values 1 kQ and 4 Q are connected in series across a constant
3.
voltage supply of 100 V. A voltmeter having an internal resistance of 12 kQ is connected across the
4 k2 resistor. Draw the circuit and calculate
(a) true voltage across 4 k£2 resistor before the voltmeter was connected.
(b) actual voltage across 4k2resistor after the voltmeter is connected and the voltage recorded
by the voltmeter.
(c) change in supply current when voltmeter is con-
nected.
(d) percentage error in voltage across 4 kN resistor.
