Find the thevenin equivalent resistance from the capacitor point of view
Relevant Equations
no equation needed just the diagram
Good day
I have a problem to find the equivalent resistance from the capacitor point of view

the solution says it's R1 but for me we still have R2 and R3 we have not deal with !
many thanks in advance

If that's your attempt at solution, you didn't try very hard.

The schematic shows an open switch S. If the switch was closed, the equivalent would be different. So how would you make the equivalent with the switch open?

the question is with switch open :)

What is the usual procedure for finding the Thevenin resistance?

From Fig.2 in order to calculate Rth we have to short circuit the E source and then R2 and R3 in series are short-circuited and only R1 remains in calculation loop.
