CBSE Class 10 Answered

Dear student,

When a total current  I_P is passed through  parallel connected resistances R₁ and R₂, the voltage V_P which appears across the parallel circuit is:
V_P = I_PR_P = I_PR₁R₂ / (R₁ + R₂)

The currents I₁ and I₂ which pass through  the respective resistances  R₁ and R₂ are:
I₁ = V_P / R₁ = I_PR_P / R₁ = I_PR₂ / (R₁ + R₂)
I₂ = V_P / R₂ = I_PR_P / R₂ = I_PR₁ / (R₁ + R₂)

Hence Assuming I₂ to be the current passing through the 2 ohm resistor,

0.8 amps.

Hope this helps.

Regards
