Maximum Power Transfer

[[email protected]]

Dear all experts,


1) If i were to connect a simple circuit to determine the effects of
capacitance in Maxim Power Transfer, how will the capacitance values
affect the Maximum Power? What's the best capacitance to be used?

2) In Nodal Analysis, how can the frequency of the signals affect the
circuit currents? How can we minimise the currents with different
frequencies instead of using resistor?

3) In a simple circuit which has a load, what's the simplest way to
know its impedance? What's the difference between resistance &
impedance?

Thanks... sorry for asking simple and silly questions.

Regards,
Albert

Hi,

You don't say what you mean by "simple circuit". Also, it would help
if you said more about your application. (And if the application is
that you're solving a homework problem, you're not likely to get the
answer in here.)

Dear all experts,

-------------
0, providing that the source has negligable inductance. have you been asked
to determine the best capacitance to use when the source is inductive. It
can be found -If this is homework, you will have to work it out.

2) In Nodal Analysis, how can the frequency of the signals affect the
circuit currents? How can we minimise the currents with different
frequencies instead of using resistor?

-------
Nodal analysis is at a single frequency. All that frequency will do will is
to affect L and C impedances. Hint- look up parallel resonance.

3) In a simple circuit which has a load, what's the simplest way to
know its impedance? What's the difference between resistance &
impedance?

---------
a) measure it.
b) impedance includes the wL and =-1/wC terms where w =2*pi*frequency
Z=R+j(wL-1/wC)

If you are asking these questions, you are missing the basis of AC circuit
analysis and need to go back to review it.
Get a textbook or Schaum's Outlines on circuit analysis.
