I have to find the Requivalent and all of the currents and voltages in the circuit below.
l------------Resistor 1----l---------l
l l l
battery l l
l Resistor 2 Resistor 3
l l l
l l l
-----------------------------------l
My picture is not showing up right, so I'll try to describe it. The battery is on the left and the wire moves up to the right where resistor 1 is. The wire continues, but splits into two paths (making a parallel). The wire turns to the right, where resistor 2 is, but if you keep going straight and then turn right, that's where resistor 3 is.
they give us the following:
R1=40 ohms
R2=60 ohms
R3=60 ohms
Vtotal=120 V
I am not sure where to even start. I know V=IR, and I-V/R, but I don't know how to find the other numbers. I also know that in a series, current stays the same while voltage changes, while in parallel, current changes, while voltage stays the same.
I also know that for series, the Req= R1+R2, while in a parallel, 1/Req=1/R1+1/R2
I just can't figure out the numbers when you have a parallel in a series. Can you help me get started?
