Relationship Between Voltage and Duty Cycle in Pulse Width Modulation (PWM)Pulse Width Modulation (PWM) is a technique that regulates the average output voltage by controlling the duty cycle of a switching signal. PWM is widely used in applications such as motor control, power management, and LED dimming. Understanding the relationship between voltage and duty cycle in PWM is crucial for correctly using and designing PWM systems.1.Basic Principle of PWM PWM Signal: A PWM signal is a periodic squ

The Concept of the Law of Conservation of EnergyThe Law of Conservation of Energy is a fundamental principle in physics that states the total energy in an isolated system remains constant. In other words, energy cannot be created or destroyed; it can only be transformed from one form to another or transferred from one object to another.1. DefinitionThe Law of Conservation of Energy can be stated as follows:In an isolated system, the total energy remains constant throughout any process.Energy can
