Are the two underlined equations at the bottom correct (can I calculate an equivalent resistance for the time constant)? I understand how to find voltage and current for each element at time t supplied with DC voltage. So I’m looking at discharging two ways. Are they both appropriately solved?
Also I've just understood Thevenin equivalent circuit(s) solutions to these circuits so I specifically want to know if the time constant can be calculated by an equivalence resistance. Thanks guys I'm excited about every second I'll be a part of this forum!
