Determine the equivalent resistance of circuit:
Determine the equivalent resistance of network across the source terminals and find the current drawn from the source.
Figure
Solution
After solving both the parallel branches, we obtain
R_{eq }= 4 + 0.67 + 2.9 = 7.067 Ω
∴ The current drawn from the source
I = V / R_{eq} = 100 /7.067 = 14.16 Amp .
