Yet Another Electricity Question?

Question

Ok I have a circuit. It has two sqwiggle lines on the sides and one on the bottom.

I know:

V(T) = 60V

I(T) = 2A

V(R2) = 30V

R(3) = 30 Ohms

now knowing all that, I need to find:

V(R3)

R(2)

R(1)

I think it's called a series-parallel circuit or maybe just a series. Not sure.

If you could help find those 3 I'd appriciate it. Thanks.

Answer 1

That's the whole problem. Squiggles are resistors...

V(R3)= 2 * 30 (( 2=I curent on circuit) 30 is Resistance on R3)
V=I * R Ohms law

R(2) = 60/30 (I=E/R)

R(1) = Using the previous answers fill in the blanks for the other resistances and voltages and you can find R1.
I almost solved it all for you.
Just remember
V=I*R
I=V/R
R=V/I
