# Need help with a potential divider question watch

Announcements
1. I've come across this question and I don't understand how to get the right answer, please could someone explain?
What is the potential at G, the mid point between the two resistors, in circuit (F)?

2. First find the total resistance of the parallel resistors (1/Rt=1/R1+1/R2) then find the current by using I=V/R.
Find the voltage/potential drop of the resistance of the parallel resistors.
Subtract the potential/voltage drop from the emf and that should give you the voltage/potential at point G.
Hopefully that will give you the answer you're looking for

Thanks, this gave me the right answer!
