The current $I_1$ (in A) flowing through $1\,\Omega$ resistor in the following circuit is

JEE Main · 2020 · 07 Jan 2020 · Shift 1 · Current Electricity

The current

I_{1}

(in A) flowing through

1 Ω

resistor in the following circuit is

Answer: (C)

The source drives a total current

I = \frac{V}{R _{total}} = \frac{1}{2.5} = 0.4 A

. The two equal

1 Ω

resistors sit in parallel, so this current divides equally between them, and the current through the chosen

1 Ω

resistor is

I_{1} = \frac{0.4}{2} = 0.2 A
