- Current divider rule for 'two' parallel resisters:
Current in any branch is given by:
\(I_1 = I \times{R_2 \over R_1+R_2}\) and
\(I_2 = I \times{R_1 \over R_1+R_2}\)
where I1 is the current in that branch, I is the total current, R1 is the resistance of that branch, and R is the total equivalent resistance.
Calculation:
Applying the current divider across 20 Ω
The Current across 20 Ω = \(\frac{5\times \frac{40}{3}}{\frac{40}{3} +20}\) = 2A
