What is negative voltage?

Negative voltage refers to a voltage that produces an opposite polarity of electric charge compared to a positive voltage. In other words, negative voltage creates a flow of electrons from a lower potential to a higher potential, which is opposite to the conventional direction of current flow. Negative voltage is commonly used in electrical circuits to power electronic devices and to control the behavior of semiconductor components such as diodes and transistors. The negative voltage can be generated using different methods such as voltage dividers, inverters, voltage regulators, and transformers. Negative voltage is important in many applications like audio processing, signal conditioning, image processing, and power supply circuits. However, special care should be taken to avoid electric shocks and damage to the equipment when dealing with negative voltage.
