Hey Mate..
The equivalent resistance when three resistance are connected in parallel.
Let I1, I2, I3- current in
R1,R2,R3_ in resistance.
The main current is _ I= I1+ I2+I3
BY OHM'S LAW :
I1=V/R1. ..... 1.)
I2= V/R2....2.)
I3= V/R3....3.)
SO, THE ADD all this.
so we use.
I=I1+ I2+I3
so...
the answer is..
1/Rp = 1/R1+ 1/R2 + 1/R3
I HOPE THE ANSWER YOU GET.
THANKS.
