The switch in the figure has been open for a very long time. The switch is closed at t= 0s.
a. At t= 0s, what are the currents in the three resistors?
b. After a very long time, what are the currents in the resistors?
Concept: initially, capacitor is shorted, and
after a long time, capacitor is fully charged, so there is no
current through the capacitor. We use this along with Ohm’s law to
find the currents as shown below ***************************************************************************************************
This concludes the answers. If there is any mistake or
omission, let me know immediately and I will fix
it....
