Voltage electric, explain, symbol, unit
Electric voltage or electric tension is the difference between two certain points, and this difference is what allows the flow of electric current from one point to another, and the voltage difference is what generates a driving force that pushes the current in the direction of the low voltage.
The unit of measured voltage :
the unit of measurement of electrical tension in the global system is Volt, which is denoted by the letter V, to measure electrical tension we use a device that called avometer or Multimeter and it is placed in parallel with the load that we want to measure its electric voltage .
