the equivalent resistance of the circuit textitR = (3 × 1 2/3 + 1 2) = (3 6/1 5) = (1 2/5) Ω ∴ Current in circuit, textitI = ( textitV/ textitR) =(4 ⋅ 8/((1 2)5))=(4 ⋅ 8 × 5/1 2)=2A

Q. The current $I$ in the given circuit is

$1.6 A$

$2.0 A$

$0.32 A$

$3.2 A$

the equivalent resistance of the circuit
$R = \frac{3 \times 12}{3 + 12} = \frac{36}{15} = \frac{12}{5} Ω$
$∴$ Current in circuit, $I = \frac{V}{R}$
$= \frac{4 \cdot 8}{( \frac{12}{5} )} = \frac{4 \cdot 8 \times 5}{12} = 2 A$
