Stunning 👍🏿

[@AsitBar-i5v]

Nicely explained.

[@dushyantsinhdabhi4772]

Here, you assume R1=R2=R3
and later R3>>>R1
Which one needs to be considered?

[@AmitBar-Analog_Circuits]

You can assume any of these

[@dushyantsinhdabhi4772]

ok, if we assume R1=R2=R3=R
Then final answer for the time constant of the circuit is
(RC)/3
Right?

Sir why C1 path is neglected during oc test

[@Ugur1982]

At the start all caps are discharged - meaning that both poles of C1 would be at GND (since the bottom plate is already at GND). So, for the initial condition, one can assume that C1 has been shorted out. Once the circuit is in transient, it would charge up to r3/(r1+r3) with the time constant that Amit has calculated.

Who IR2 = 0
And making R2 as short not convenience for me

[@sumanbaur3021]

Dada I am suman. Recently I sent a message regarding how to have a mock interview. You have accepted my LinkedIn invitation. You told me to mail you but how get your email id?
