Question

Find out the total current flowing in the circuit as shown in above figure ?

• A. 4A
• B. 3A
• C. 2A
• D. $\frac{4}{3}A$
• E. $\frac{3}{4}A$

Answer 1

The correct option is B 3A

Equivalent resistance between points C and D, $R_{AB}=2+2=4\Omega$

Total resistance of the circuit $R_T=\frac{R_{AB}\times 2}{R_{AB}+2}=\frac{4\times 2}{4+2}=\frac{4}{3}\Omega$

Total current in the circuit $I=\frac{V}{R_T}=\frac{4}{4/3}=3$ A
