Find the voltage across the 4Ω resistor (resistor 3).
This is all show in the pictures provided:
I have started by reducing all the resistors into one resistor, but please take a look over my working and tell me if it's all correct.
After reducing all the resistors into one, I used the resistance to calculate the supply current.
Then, with the supply current, I calculate the voltage over the first resistor. I then subtracted the first resistors voltage with the supply voltage to work out resistor 2's voltage.
At this point I'm stuck. I don't understand where to go from here to work out the voltage over the 4Ω resistor. I know I haven't got long to go
