Current Electricity Question 15

Question 15 - 2024 (29 Jan Shift 2)

In the given circuit, the current in resistance $R _3$ is :

(1) $1 A$

(2) $1.5 A$

(3) $2 A$

(4) $2.5 A$

Show Answer

Answer: (1)

Solution:

$R _{eq}=2 \Omega+2 \Omega+1 \Omega=5 \Omega$

$i=\frac{V}{R _{eq}}=\frac{10}{5}=2 A$

Current in resistance

$$ \begin{aligned} R _3 & =2 \times\left(\frac{4}{4+4}\right) \\ & =2 \times \frac{4}{8} \\ & =1 A \end{aligned} $$
