Hi guys,
I have this homework question that i have attached. I've done a couple questions but I'm not sure if they are right.
For the first question i arrived at 15.49 by rearranging the formula; energy stored=1/2.C.V^2. when rearranged you get the square root of 240 for voltage.
For the second question b I don't understand how you find V. Is this the same as Vs? OR do you have to find the equivalent circuit by having all the inductors behave as a short circuit and capacitors as an open circuit since the circuit has reached a steady state.
For the third question I think i need the answer from b to continue.
For the fourth question i used the formula of power=V^2/Resistance. So 15.49^2/92 = 2.608mW
Not sure if this is right though.
Any help would be appreciated.
Thanks
