Voltage – What is voltage and types?

The Voltage is described as a thrust behind the electricity. Stress can be too referred to as potential difference, electromotive force (EMF) or electrical pressure. Imagine electricity as water flowing through a hose. The pressure (Voltage) is what causes the water (current) to flow out of the hose end. The unit of measurement for voltage is the volt, and the letter for voltage is “V” unless it is used in the formulas to Calculate voltage. In this case, the letter “E” denotes the electromotive force. The voltage is calculated by multiplying current and resistance. This formula is known as Ohm’s law.

What is voltage and types?

Voltage, also known as electric potential difference, is a measure of the electrical potential energy per unit charge between two points in an electric circuit. It represents the force or pressure that pushes electric charges to flow in a circuit.

Voltage is typically measured in volts (V) and is denoted by the symbol “V”. One volt is equivalent to one joule of energy per coulomb of charge.

There are different types of voltage sources or potential differences in electrical circuits:

1. Direct Current (DC) Voltage: This type of voltage remains constant in magnitude and direction over time. It is typically produced by batteries or power supplies that provide a steady flow of electrons in one direction.

2. Alternating Current (AC) Voltage: AC voltage periodically changes its magnitude and direction over time. It is the type of voltage supplied by power grids and is commonly used for electrical power transmission. In AC voltage, the direction of electron flow reverses periodically, typically at a frequency of 50 or 60 hertz (Hz).

3. Peak Voltage: Peak voltage refers to the maximum value reached by an alternating voltage waveform. It represents the highest potential difference between two points in an AC circuit.

4. RMS Voltage: Root Mean Square (RMS) voltage is a way to express the effective or equivalent voltage of an AC waveform. It is the value that, when applied to a resistor, would produce the same amount of power as the corresponding DC voltage. The RMS value is typically used to represent the voltage in AC circuits.

5. Pulsating DC Voltage: Pulsating DC voltage is a type of voltage that has a unidirectional flow but with variations or fluctuations in its magnitude. It is usually encountered in circuits where rectification of AC voltage is done, resulting in a voltage that retains some ripple or fluctuation.

These are some of the common types of voltage in electrical circuits, each with its own characteristics and applications.
