(c, d)

From the loop badb, 2i 1 – 2 + 1+ i 1 + 2(i 1 – i 2 ) = 0

5i 1 – 2i 2 = 1 … (1)

From the loop dcbd, - 3 + 3i 2 + i 2 + 1 – 2(i 1 – i 2 ) = 0

or, – 2i 1 + 6i 2 = 2

From eqs. (1) and (2),

i 1 = amp, i 2 = amp

So, i 1 – i 2 = amp

∴ V b – V d = volt

The PD across the cell is:

V c – V d = – 3i 2 + 3 = volt

The PD across the cell is:

V c – V b = i 2 + 1 = volt
