Can anyone help with a calculation please ?

Hey. Basically, we are doing alot of calculations in college at the moment on resisors in series and parallel circuits. Iv pretty much got everything down apart from calculating current in the parallel branch of the circuit.

I have a couple of ideas which may be the way to do it, "or not" im not sure...

Do i A.) divide the voltage over the highest resistor total or B.) Add all the resistors on the parallel together then divide the voltage over the total that i get ?

I would just ask the tutors, but im not in college until friday and i cant seem to get my awnsers anywhere eles online. So your help would be amarrrrzzzing.

Whitey.

To get the branch current you need the total resistance of the branch, you then divide the voltage across the branch by its total resistance. To get volt drop across each resitor you multiply the branch current by the individual resitors value.
