Noun
Voltage refers to the difference in electric potential between two points. In a static electric field, it represents the work needed to move a unit of charge between these points.
Mathematically, voltage is represented by Ohm's Law as V = IR, where V is the voltage in volts, I is the current in amperes, and R is the resistance in ohms.
Voltage can be of two types: alternating current (AC) or direct current (DC). Alternating current (AC) flows in undulating sine waves and reverses direction at regular intervals. This type is commonly used in homes and businesses as it can be easily transmitted over distances. Direct current (DC) flows in a straight line and in one direction, typically sourced from batteries.
Example of Voltage in a sentence:
"Voltage can be described as the force that pushes current around in a circuit."
Synonyms: electromotive force, electric pressure
