Hi
I am having trouble with the following question:
View attachment tut4qns.doc
For the first question i got the answers for a) however the energy for the 20 and 40 micro ohms capacitors are incorrect.
This is what i did:
sub 0.5 into the equations that i got for a) and i get
v1 = 840.150v
v2 = 208.030v
w_12 = 0.5 * (12 * 10^-9) * v1^2
=4.23J
w_20 = 0.5 * (20 * 10^-9) * v2^2
=0.424J
w_40 = 0.5 * (40 * 10^-9) * v2^2
=0.866J
Question 2 how would i start it?
P.S
