What Is 1 Volt? Understanding Voltage and Electric Potential

Learn what 1 volt means and how voltage drives current flow by measuring electric potential energy per unit charge in circuits.

0 views

1 volt is defined as the difference in potential between two points of a conductor when a current of one ampere dissipates one watt of power between those points. Simply put, voltage is the measure of electric potential energy per unit charge. It drives the flow of current in circuits, similar to how pressure pushes water through pipes.
