Question

The ammeter reading in the circuit of Fig. is –

A

$\frac{15}{32}$ A

B

$\frac{14}{33}$ A

C

$\frac{17}{33}$ A

D

$\frac{15}{31}$ A

Answer

$\frac{15}{32}$ A

Explanation

Solution

E_eq = $\frac{3 \times 1 + 6 \times 2}{1 + 2}$ = 5V, r_eq = $\frac{2 \times 1}{2 + 1}$ = $\frac{2}{3}$ Ω

I = $\frac{5}{10 + 2/3}$ = $\frac{15}{32}$ A
