Question attached in PDF form.
As far as what I've done, I wrote up the condition required while the voltage across the SCR is less than 5v
x(t)=6V+(0-6)e^-t/τ
after the switchover, I'm having difficulty writing the equation, as I don't understand what the voltage difference would be across the SCR at t=∞.
At t=0, I know it will be 5v, because that's what it is before the changeover.
Any help on even how to set up the equation will be appreciated- I know it's simple, and I'm just blanking on it.
