Hi all,

Im having a bit of trouble answering two questions on a past paer.

Q1) What are the three principle features of an ideal operational amplifier or op-amp??

Q2) Draw the power triangle relating active power, P, reactive power, Q, apperent power, S and the power factor angle.

Any ideas on how to answer the questions, been looking through all my notes and can't seem to find anything.

Thanks, Ammo
