Voltage, also known as electric potential, is a measure of the potential energy difference between two points in an electric field. It is commonly measured in units of volts (V) and represents the amount of work required to move a unit of electric charge from one point to another.
Voltage and current are two different measures of electricity. While voltage is a measure of the potential energy difference between two points, current is a measure of the flow of electric charge. In other words, voltage is the driving force that causes current to flow.
The amount of voltage in a circuit is determined by the source of the electricity, such as a battery or power outlet. Other factors that can affect voltage include the number of cells in a battery, the type of material used in the circuit, and the distance between the two points where the voltage is measured.
High voltage can be dangerous because it has the potential to cause electric shock, burns, and even death. Touching a high voltage source can result in a large amount of electric current passing through the body, which can disrupt the normal functioning of the heart and other vital organs.
Voltage is used in a variety of ways in everyday life. It is essential for powering electronic devices, such as phones, computers, and household appliances. It is also used in transportation systems, such as electric cars and trains. In addition, voltage is used in medical equipment, lighting systems, and many other applications.
