Explanation / Answer

a)

Net emf on the circuit is

Enet =1.5+1.5+1.5+1.5+1.5+1.5-1.5-1.5=6 V

b)

equivalent resistance

Req =(1/38 +1/14 +1/22)-1+12+8=26.98 ohms

Req=27 ohms

c)

Current through each cell of the battery is

I=Enet/Req =6/27=0.222 A

d)

Current through each resistor

I1=I5=0.222 A

I2=0.222*[(1/14+1/22)-1/38+(1/14+1/22)-1]=0.0408 A

I3=0.222*[(1/38+1/22)-1/14+(1/38+1/22)-1]=0.111 A

I4=0.222-0.0408-0.111=0.0707 A

e)

V2=I2R2=0.0408*38=1.56 Volts

f)

Power generated by battery A is

PA=(1.5+1.5+1.5+1.5+1.5+1.5)*0.222=2 Watts

g)

Power generated by battery B

PB=(1.5+1.4)*0.222=0.666 watts

h)

power generated by batteries

P=6*0.222=1.332 Watts

i)

P3=0.1112*14=0.17 Watts

j)

P4=0.07072*22=0.11 Watts

k)

VAB =(1/38 +1/22+1/14)-1*0.222=1.55 Volts

l)

VAC=[(1/38 +1/22+1/14)-1+12]*0.222=4.21 Volts
