Question

2. Determine the current in the 4ohm branch in the circuit shown​

Answer 1

Explanation:

In parallel resistances, the potential difference across them is same.

Potential difference across PM

V = 4 x 1 = 4 Volt (ie, across 4 Ω)

Equivalent resistance of lower side arm,

Therefore, 3.2 A current ows in 1 Ω resistance, hence potential difference between M and N is

V' = 3.2 x 1 = 3.2 volt
