transistor amplifier frequency

Suppose I made a simple transistor amplifier using one NPN transistor, one resitor between collector and + of battery and one resistor between NPN's base and + of battery. This amplifier uses capacitor coupling. (that is, a capacitor is placed between the source and the base of the transistor, and a capacitor is placed between the collector of the same transistor and the output.)

What I am describing is a simple, capacitor coupled transistor amplifier.

Suppose that every value is given in the circuit (including transistor hfe and input frequency).
What equations can I use to obtain the values for power and frequency?

hi
mstechca
the circuit u described is a Common emmiter type amplifier circuit.
You can plot the frequency response of the BJT if u know internal capacitor values, and calculate gain frm it.
else better use SPICE simulations.
