Which formula relates power consumption to frequency and voltage?

The formula that relates power consumption to frequency and voltage captures the fundamental relationship in electronic circuits and power systems. Power consumption in digital circuits, for example, is largely determined by the dynamic power equation, which can be expressed as:

Power = C × V² × f

Here, C represents the capacitance, V denotes the voltage, and f signifies the frequency. This relationship highlights that power consumption is proportional to the square of the voltage and directly proportional to the frequency of operation.

Understanding this formula is crucial for optimizing energy efficiency in systems, especially for CPS (Cyber-Physical Systems) where both performance and energy consumption must be balanced.

This formula is particularly relevant because it illustrates how adjustments in either voltage or frequency directly affect the power consumption of a system, which is a key factor in energy management practices.
