PHYS345 Electricity and Electronics

Hint for D7.12

For 0 < t < 3 s (when the switch on the right is still closed), consider a Thevenin generator that can replace the voltage source and the two resistors as a way of determining the time constant for discharge of the capacitor.

For t > 3 s, the capacitor continues its discharge with a different time constant through the single 2 ohm resistor after the second switch is opened.
