Question

In the following network of wires, the value of current $i$ is


$[$0.77 Mark$]$

• A. $2\text{A}$
• B. $3\text{A}$
• C. $8\text{A}$
• D. $6\text{A}$

Answer 1

The correct option is C $8\text{A}$

According to Kirchhoff’s junction law, at the junction given in the circuit,

Total incoming current = Total outgoing current

$\Rightarrow 2+10=4+i$
$\Rightarrow i=12–4=8\text{A}$
