So I've got a circuit exam tomorrow, and the only kind of exercises I'm having trouble solving are RL or RC circuits with an impulse source.

Pic is an example, where Rb=10kohms, r_pi=1kohms,g_m=0.1S, Rs=Re=Rl=1kOhms and Vs=δ(t). I need to fine the Vc(t) function of the voltage across the capacitor without using the laplace domain, and I'm drawing a blank

Why would any label have to be Pi
Also what is S?

And the arrow box is a current source right?

usually represents the base-emitter resistance in the hybrid pi model of a transistor

Ok I will have a look at it

Threads like these are way better than the prove that 1 is a number, prove that you exist, define zero haha pro tip you can't and the my iq is higher than yours threads

Using Nodal Analysis would probably help

It's a transistor model. Usually the resistance between emitter and base is labeled R_pi

Threads like these are homework threads. Boring as fuck, because shit like this is just solving matrices. I don't understand why you would even think this is a good type of thread.

What is the frequency of Vs and capacitance of C?
