Question

The circuit diagram in Fig. 8.53 shows three
resistors 2Ω, 4Ω, and RΩ connected to a battery
of e.m.f. 2 V and internal resistance 3Ω. If main
current of 0.25 A flows through the circuit, find :
(a) the p.d. across the 4Ωresistor,
(b) the p.d. across the internal resistance of the cell,
(c) the p.d. across the RΩor 2Ωresistor, and
(d) the value of R.
​

Answer 1

Answer:

(b) the p.d. across the internal resistance of the cell,
