Question

In the circuit shown in the figure, the current through

Moderate

A

the $3 Ω$ resistor is 0.50 A
B

the $3 Ω$ resistor is 0.25 A
C

the $4 Ω$ resistor is 0.50 A
D

the $4 Ω$ resistor is 0.25 A

Solution

Equivalent resistance of the circuit, $R = 9 Ω$
$∴ Main current i = \frac{V}{R} = \frac{9}{9} = 1 A$
After proper distribution, the current through $4 Ω$ resistor is 0.25 A.
