thanks guys :) i appreciate it! can anyone tell me why r4 is not considered when calculating the current (using the equation given by nacer) would i just have to apply that formula to the diagram above to find the norton current?

ok forgive my naivety but what do the double backslashes indicate? // like that? i know the single one is divide. i feel really retarded now.

thanks nacer, i'd best get to work :)

hi guys, sorry to be a bothersome newbie but i have another electrical query. this time its nortons theorem. i need to determine the current through RL, the voltage across RL and the power developed in RL using the theorem. any pointers on where to start would be really appreciated :!)

hey, i think i figured it out ( i hope) i used the thevenin circuit and added in the RL resistor. i then found the total resistance by addin them both together and then found the current V/total resistance. with the current i found the voltage across RL and finally the power developed across RL...

hi antoker, thanks for all this help :smile: I've scribbled down what u told me and i found the thevenin voltage at terminals ab to be 9.94V. i then found the thevenin resistance to be 9.73 ohms. how would i go about adding RL back into the circuit so i can find the current across it etc?

thanks antoker, i really appreciate your help. I am so useless at electrical engineering. its by far my weakest subject :rolleyes:

hi, i tried to make an equivalent circuit but I am really quite useless at this. I've only just began studying this module! the problem is that my textbooks only have examples of thevenin circuits with one resistor parallel to the battery where as this question has 2. this is why I am confused...

oops. I am sorry bout that. i didnt realize there was a coursework section. thanks for moving the thread:approve: thank u for the replies as well guys. i managed to make two thevenin equivalent circuits from terminals a and b and c and d. is that correct? i found the voltage values from this but...

practice exam question HELP PLEASE! hi guys, I've been going through my past exam papers and i found this question. my lecturer says that a similar question will be on my exam but i haven't got any idea how to do it :cry: can anybody help me please? i have to determine the current through...
