How do amplifiers follow the law of conservation of energy?

Amplifiers are like women. A woman is given an input as a signal from a man, she processes the input according to her design and characteristic function, and after nine months there is an output bigger than the input. read more

Transistor do not break the law of conservation of energy. Actually transistor is not amplifying the signal. Transistor is a variable resistor. When input voltage applied to Base, it changes the resistance between the Collector and Emitter. To understand how an amplifier works, you need to first understand how a Voltage Divider circuit functions. read more

As energy is transferred to ice, the attraction between water molecules is broken and the ice melts. As water vapor releases energy attraction between molecules increases, and liquid water condenses. State the law of conservation of mass and the law of conservation of energy and explain how they apply to changes of state. read more
