Answer 1

1)resistance in parallel =

1/resistance = 1/2 + 1/6

1/resistance = 4/6

1/resistance = 3/2

1/resistance = 1.5ohm

(Now 1.5 ohm is in series)

Resistance in series = 1.5 ohm + 2 ohm + 0.5 ohm = 4ohm

So,total resistance is 4 ohm.

2)to find the total current we have formula:- Potential difference = Current × Resistanc(V =IR)

V = 9volt

R = 4 ohm

So, 9 volt = I×4 ohm

I = 9/4 =2.25 Ampere

So the total current is 2.25 Ampere.

3)total resistance in parallel =1.5 ohm(from 1st answer)

V = 2.25 ×1.5(V=IR)

V = 3.375volt

So total potential difference in parallel is 3.375 volt.Potential difference dont change in paralle combination so current in 6 ohm will be:- V =IR :- 3.375volt = I×6ohm

Thus I =3.375/6=0.5625Ampere.

4. V=IR

V = 2.25 volt ×2 ohm+1.5volt ×2.25ohm

V = 4.5volt +3.375volt

V =7.875volt
