What is a Volt?
A volt (V) is the SI unit for electrical potential difference. It measures the "pressure" that pushes electric charges through a circuit. One volt is defined as the electrical potential difference that would drive one ampere of current against one ohm of resistance.
Common Applications
Volts are used everywhere in electronics and electrical systems. Common examples include: household outlets (120V or 240V), batteries (1.5V, 9V), USB ports (5V), and power transmission lines (thousands of volts).
Conversion Tips
When converting between voltage units, remember: 1 kV = 1,000 V 1 V = 1,000 mV 1 mV = 1,000 µV
