Question

a battery of emf 3v is connected in series with 10ohm and with a parallel combination of resistances of 3ohm and 6ohm calculate i) resistance of parallel combination ii) current in the circuit​

Answer 1

Answer:

R=12Ω

I=0.25A

Explanation:

V=3v

R1=10Ω

R2=3Ω

R3=6Ω

R=?

I=?

           1/R'=1/R2+R3

           1/R'=1/3=1/6

           1/R'=1/2

            R'=2Ω

           

           R=R1+R'

           R=10+2

           R=12Ω

           V=IR

           3=I*12

           I=3/12

           I=0.25A
