Current Question (ID: 16707)

Question:

$\text{The figure below shows a network of currents. The current } i \text{ will be:}$

Options:

1. $3 \text{ A}$
2. $13 \text{ A}$
3. $23 \text{ A}$
4. $-3 \text{ A}$

Solution:

$\text{Hint: The net current at any junction is equal to zero.}$ $\text{Step: Find the current } i \text{ in the given circuit.}$ $\text{Apply Kirchoff's current law in the given circuit we get:}$ $\sum I = 0$ $15 + 3 + 5 - i = 0$ $\Rightarrow i = 23 \text{ A}$ $\text{Hence, option (3) is the correct answer.}$
