Answer 1

Answer:

Explanation:

(i) Resistors R2 and R3 are in parallel,

so,1/R2+1/R3=Req.

1/Req.= 1/8+1/12=5/24

Req.=24/5=4.8 ohm

Now, R1 and Req. is in series

so, R1+Req.=Rfinal

Rfinal=7.2+4.8=12 ohm

(ii)V=IR

V=6V

R=12 ohm (from above)

6=12 X I

I=1/2 A=0.5 A

(iii)V=IR

R=7.2 ohm

I=0.5 A (from above)

V=7.2 X 0.5=3.6 V
