Hello there,
I'm a new learner and would like to know how to find the total resistance of the following question that I have attached. I have the correct answer; 100 ohms... but I need someone who could help me how solve it and please explain it to me. Thank you.

 

Look at R1 and the resistor network, Try to see how the conductor path attaches directly to R1, and simply shorts around the elaborate network.

 

A resistance placed in parallel to a short circuit is equivalent to zero resistance.
the whole of the resistance containing network is parallel to a short circuit.

oops Mr. Beenthere beat me to it.

 

Is it possible that you have redrawn the circuit incorrectly? If not, then your instructor has made the circuit appear much more complex than it actually is. This is what beenthere and recca02 have referred to in their replies.

Your answer is correct by the way for the circuit as drawn.

Thank you alot beenthere, recca02, and hgmjr for the help.
