Find the voltage and the current through R5
The Attempt at a Solution
* To find Vth:
1- Open circuit R5.
2- Find the voltage at A and B by determining the current through R1, R2, R3 and R4 (Their Req=(R1+R4)//(R2+R3)=368.4 ohms
3- The current is equal to 0.24 A, hence the Vab=Vth=30V
* To find Rth (=Rab):
1- Open circuit R5 and short circuit the voltage source.
2- (R1+R4)//(R2+R3)=368.4 ohms
My problem is here, does the wire (caused by short circuiting the source) cause short on (R1+R4)?
