How do active components produce power in terms of current or voltage
Using a transistor, as an example of an active component, has the potential to modify the current or voltage on its outputs compared to its input. A passive component like a resistor does not.
A transistor used as a amplifier modifies the lower signal input to a higher signal output.
Without getting into a deep dive on active component technologies and how they are built to accomplish the task. Let's use the block diagram and think of the box as an active component. Any signal entering on the left side is modified by a factor of 5. 1V in become 1V out. The active components has amplified the signal.
You could reverse the box and the active components is designed to reduce the signal.
If the input signal was a varying sine wave the output would be a the sine was at a higher amplitude.
