Description: Overvoltage refers to a temporary increase in voltage that exceeds normal operating levels of an electrical circuit. This phenomenon can be caused by various reasons, such as electrical discharges, failures in the power grid, or even equipment switching. Overvoltages can be harmful to electronic components, as they can cause irreversible damage, malfunction, or even total destruction of circuits and devices. In the context of electronics and electrical engineering, overvoltage is a critical aspect to consider in the design and implementation of circuits, as microcontrollers and other components are particularly sensitive to voltage variations. To mitigate the effects of overvoltage, protection devices such as varistors, clamping diodes, and fuses are used to help safeguard circuits from voltage spikes. Understanding overvoltage is essential for electrical engineers and circuit designers, as it ensures the reliability and durability of electronic devices in various applications.
