For the circuit shown in the following diagram, What is the value of
1. current through 6Ω resistor?
2. potential difference across 12Ω ? [3 MARKS]
Each point: 1.5 Mark
1. For current through 6 Ω
Current from 4 V battery flows through first parallel branch having 6Ω and 3Ω in series.
Current in this branch
I = 49 = 0.44 A
2. For p.d. across 12Ω
Current through second parallel branch
I = 415 A
P.D. across 12Ω , V = 415×12=3.2V
