Why resitence is multiplid by 3 ?

Because we are taking 3 resistance of same value if the values will be diff. Then we so for normal method.

Equation should be
Req=R/N
Req=R1/1+R2/1+R3/1
Req=47/3
Req=15.6 ohms
I=V/R
I=110/15.6
I=7.06 A
Req=R/N
Req=R1/1+R2/1+R3/1
Req=47/3
Req=15.6 ohms
I=V/R
I=110/15.6
I=7.06 A

1/R=1/R1+1/R2+1/R3=1/47+1/47+1/47=3/47
R=47/3=15.67
I=V/R=110/15.67=7.06A
R=47/3=15.67
I=V/R=110/15.67=7.06A

Given 3 resistances are connected in parallel.
Each resistance value (R) = 47 ohm.
Two resistance value is 23.5.
Resistance 23.5 is parallel to another 45ohm resistor.
The value of (Req) =15. 66.
We can know formulla I=V/R.
The value of (I) is=7.02A The approximate answer given problem is 7.6.

V = IR,
V = 110,
R = 15.6{Parallel in resistance so, r = 1/r1+1/r2+1/r3(3 phase)}.
I = V/R = 110/15.6 = 7.06V.
V = 110,
R = 15.6{Parallel in resistance so, r = 1/r1+1/r2+1/r3(3 phase)}.
I = V/R = 110/15.6 = 7.06V.

Parallel in resistance is same value r/n = 47/3 = 15.66.
Rt = 15.66.
V= 110.
I = 110/15.66 = 7.06v.
Rt = 15.66.
V= 110.
I = 110/15.66 = 7.06v.

Req- 47/3.
= 15.67.
Now,
I = V/R.
= 110/15.67.
= 7.06 amp.
= 15.67.
Now,
I = V/R.
= 110/15.67.
= 7.06 amp.

It should be 7.02 amp.
I = 110*3/47 = 7.0212 amp.
I = 110*3/47 = 7.0212 amp.
