OKz here is the question to be considered:(adsbygoogle = window.adsbygoogle || []).push({});

Determine the following values for the class A amplifier when operated with maximum possible output signal:

1)Min transistor power rating

2) AC output power

3) Efficiency

4) Maximum Load Power

okz so here is what i think about these formulae:

1) this is the power at Quiscent point. that is

P = Icq x Vceq

where Icq is simply the Ic of the circuit and Vceq is the Vcc/2

2) that would be P = 0.5 Icq x Vceq

3) Efficiency = 0.5 Icq x Vceq/ Vcc x Icq

4) for max load power, it think i should use this formula :

P = (Vc^2)/RL

where i can find Vc = Vcc - Ic Rc

where RL is the capacitively coupled Load Resistor.

Please tell me that have i written the above formulae correctly or not. If not then what are the correct formulae.

I shall be thankful to u for this act of kindness.

take carez!

Good Bye!
