Question

The total current supplied to the given circuit by the battery is, 9 A, 6 A, 2 A, 4 A

MARKS App · Accepted Answer

The equivalent circuit of the given circuit is as shown

Resistances 6

Ω

and 2

Ω

are in parallel

∴ R^{'} = \frac{6 \times 2}{6 + 2} = \frac{3}{2} Ω

Resistances

\frac{3}{2} Ω a n d 1.5 Ω a r e i n s e r i e s

∴ R^{''} = \frac{3}{2} + 1.5 = 3 Ω

Resistances 3

Ω

and 3

Ω

are in parallel

∴ R = \frac{3 \times 3}{3 + 3} = \frac{3}{2}

The current,

I = \frac{V}{R}

= \frac{9}{3 / 2} = 6 A
