Hey!

So, for Question 3, I had this doubt:

I used the formula : I= Capacitance * Delta V * Delta Time

2.5= 50* (v2-6)*(3-0). .

Is this logic right?

And can somebody tell me how to approach Q4?

 

Regarding 4.
Convert voltage source and current source into complex numbers.
For example the voltage source is 6 volts @ 0°, so it has real component that is 6, imaginery component is 0, in complex form it is 6+0j.
Once you did that, solve for V0using whatever methode you like (KCL, KVL, Node-Voltage, Mesh-Current, whatever).

 

OK!! I will do that. .

But is my Answer 3 method right?
