Answer #1

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....
