In a CE transistor amplifier there is a current and voltage and gain associated with the circuit. In other words there is a power gain. Considerind power a measure of energy, does the circuit violate conservation of energy?

Answer» In CE transistor amplifier, the power gain is very high. The circuit used does not violate the law of conservation of energy because in this circuit the extra power required for amplified output is obtained from d.c. source.
