Explanation / Answer

12 and 6 are in parallel their equivalentresistance=R1=(12*6)/(12+6)=4 4 and 8 are in parallel their equivalentresistance=R2=(4*8)/(4+8)=2.667 R1 and R2 is in series with 5 net equivalent resistance=4+2.667+5=11.667 (ans a) part b-------- current through 5 resistance=44/11.667=3.78 A potential difference across 12 resistance and 6resistance=R1*3.78=4*3.78=15.12 V current through 12 =15.12/12=1.26 A current through 6=15.12/6=2.52 A potential difference across 4 and 6=R2*3.78=2.667*3.78=10.08 V current through 4=10.08/4=2.52 A current through 8=10.08/8=1.26 A
