Explanation:

let the equivalent resistant be ' R '

So,

  \frac{1}{r} =  \frac{1}{r1} +  \frac{1}{r2}  +  \frac{1}{r3}

  =  > \frac{1}{r} =  \frac{1}{3} +  \frac{1}{5}  +  \frac{1}{7}

  =  > \frac{1}{r} =  \frac{35 + 21 + 15}{105}

 = > \frac{1}{r} =  \frac{71}{105}

so \:  \:  \: r =  \frac{105}{71}

Now total current , i = 23A

Voltage , v = ?

According to ohm's law

v \: =  \:  ir

 =  > v = 23 \times  \frac{105}{71}

 =  > v =  \frac{2415}{71}

 = > v = 34 \frac{1}{71} volt

so \:  \: v = 34.01volt

Answer:

Total resistance=6/11

Explanation:

parallel =1/Rp=1/R1+1/R2+1/R3

1/Rp=1/1+1/2+1/3

1/Rp=(6+3+2)/6

Rp = 6/11

I hope you will understand and this answer may be help you.
