What is Voltage?

Voltage means force or pressure that special force applied to any good conductors and produce result voltage, in other words applied force to conductor that force or energy have given signal to movement or flow of free electrons through the good conductor is called Voltage.

Electric potential.

Electrical potential is also called Voltage.

How to measure voltage?

Voltmeter is an instrument ot measure or calculate certain voltage in particular point.

voltmeter figure.

SI unit

The SI unit of voltage is Volt and is denoted by ‘V’.

Types of Voltage

There are two types of voltages.

  1. AC voltage.
  2. DC voltage.

AC voltage.

The movement or flow of free electrons is reverse and farward direction periodically when applied AC Voltage.

DC voltage.

The movement or flow of free electrons is only move single direction or path is called DC Voltage.

Who discovered the Voltage.

The name of Scientist “ALESSANDRO VOLTA” and he is belong to Italy and the age of Alessandro volta is b/w 1745 to 1827.
