Question

this is a circuits question - trying to find the resistance of R3 in the circuit......

Answer 1

so i figured out the currents for the 4 areas and i know what the current total is but i dont know how to find the resistor value with the info i have here...

Answer 2

i know this should be fairly simple, but i must be missing something that i need to find to find the resistance

Answer 3

This should be in physics
Remember that the potential drop along the two parallel arms are equal

Answer 4

so in that case then the voltage should be the same, resulting in V3=5v?

Answer 5

Sorry @xavier, I will put this in physics next time.

Answer 6

Awesome, thank you very much @xavier

Answer 7

Yes, thats right
