Part (a)
For series arrangement of reistors
Reff=R1+R2
=150+1000=1150Ω
Current in circuit
I=totalresistancee.m.f.ofvoltagesource
=1150127=0.11A
Part B
Effective resistance for two resistors in parallel
Reff=R1+R2R1R2=10+3210×32=7.62Ω
Total current
IT=effectiveresistancee.m.fofVoltagesource
=7.6224=3.15A
Current through a resistor in parallel arrangement
IR=Resistanceoftheresistorpdacrosstheparallelarrangement
I10Ω=1024=2.4A
I32Ω=3224=0.75A
