Hi. I am having problems finding the Req in parallel circuits. I have a problem like this
R1- 12
R2- 8
R3- 8
emf- 12
Now I know Req= 1/R1, 1/R2, 1/R3 but my homework book explains that
1/12 1/8 1/8 = (2+3+3)/24 = 8/24 = 1/3 = Req is 3 coulomb
I want to know where the 2+3+3 comes from, I have absolutely no idea how to find that.
I also have another question that says
r1-5
r2-10
r3-15
R1 1/5, R2 1/10, R3 1/15
1/5= .2
1/10= .1
1/15= .066
Req= 0.37
I know this isn't right . I have tried for awhile just by myself to figure this out (I am doing this as a home class) but I cannot do it. Someone please help me out!
