Question

In the circuit shown in the figure, the current through

• A. the 3$\Omega$ resistor is $0.50A$
• B. the 3$\Omega$ resistor is $0.25A$
• C. the 4 $\Omega$ resistor is $0.50A$
• D. the 4$\Omega$ resistor is $0.25A$

Answer 1

The correct option is D the 4$\Omega$ resistor is $0.25A$

$Req=2+2+4=8\Omega$

$\frac{1}{Req}=\frac{1}{8}+\frac{1}{8}$

$Req=\frac{8}{2}=4\Omega$

$Req=3+4+2=9\Omega$

$I=\frac{V}{Req}=\frac{q}{q}=1A$

Let total current be $I$

Current flowing through $4\Omega$ resistors

$=\frac{I}{4}$

$=\frac{1}{4}=0.25\Omega$

Current through $3\Omega$ resistor =$I$

=$1A$
