Hello
I'm hoping someone can help me with understanding how we calculate Thevenin resistance total!! I'm struggling with parallel and series resistor calculations I just can not SEE which resistors are in parallel and which one's are in series!! Example you take the load resistor out and you have a point A and point B and on the end of point A there is now a Hanging resistor so would that resistor be in parallel with another resistor in the circuit? I guess It boils down to how do I know when a resistors is in parrelel and in series when calculating RThevenin in a circuit. if you have any example please post pictures here and explain how you got Thevenin RT
Thanks for the help
Jeff

 

Check out the tutorials section of this website covering parallel and series circuits.
