NEED HELP ASAP! Wheatstone bridge and DC series/parallel ! Please look!
I have three problems I need help solving.
Problem #1:
Fine the value R1 in the figure if R2 = 30ohm, I = 0.5A and V = 10V
My try was:
Rp = R1 + R2 , 20 = R1 + 30 , R1 = -10?
** please look for attached diagram problem 1
------------
Problem # 2
You have a balanced wheatstone bridge at L2= 45cm, mark ( where L2 + L3 = 100cm ) and R1 = 100ohm, what is the unkown resistance Rx?
** please look at attached diagram for problem 2
Problem #3.
Calculate the current of A in the figure if R1 = 250ohms, R2 = 400ohms, R3 = 200ohms and R4 = 200ohms
** please look at problem 3 for the diagram attached.
I had I = V/R with 45V/450 Ohm which gave me 0.1 A I combined the resistors to 400, 400, 250 on the diagram.
