Norton Resistance question

[[email protected]]

Can someone tell me (step by step) how to calculate the Norton's
resistance for this circuit? (see picture below)

** Using Norton here is silly and time wasting.

It is simply a parallel resistor problem.

1. RL plus R3 parallel R 5 - so compute the combined value.

2. This value plus R2 parallel R4 - so compute the value.

3. Add this to R1.

You can simplify this circuit a lot by applying the rules for parallel and
series resistors repeatedly.

treat the voltage source as a short circuit (or as a fixed resistor if
it has non-zero resistance) and solve for the resitance at the part that
interests you (this would be the output terminals)

Try thevenin that is a snap. look up thevenin theory.

You are lucky today.
Usually its not easy to get someone to do your homework for you.

It's not clear from the OP's problem statement that RL should
be included in the Norton resistance, or just the network up
to RL leaving a Norton equivalent driving the load.

Exactly so. Norton's theorem applies to a two-terminal device
consisting of voltage sources and resistors. Tell us _which_ two
terminals of the seven, or there isn't any soluble problem presented.
