## 1) Voltage - Voltage is the pressure between two terminal or it is electromotive force which move a unit charge from one location to another. SI unit is ''Volt''.

#### 2) Current - It is flow rate of electric charge from one place to another, Current always flow from negative to positive. SI unit of current is ''Amp". Power Gride

The voltage and flow are the two significant parts of electricity.The voltage is the sort of the electromagnetic power whose impact causes the progression of electrical flow in the circuit. The size of a voltage and current relies upon one another, however these two terms are not the same as one another here and there. One of the significant contrasts among voltage and flow is that the voltage is the distinction between the two focuses and the flow is the progression of electrical charges between these two purposes of an electric field. Some others contrasts between them are clarified underneath in the correlation outline.

### Practical example

Assume, There are two water tanks, one is on roof and the another is on ground, when we leave water from upper tank, then the water flow with pressure and quantity. now we replace pressure into voltage and current into quantity. In this case voltage is pressure of electrons and current is quantity of electrons.

different standards of voltage and current used in every country. The voltage in India is 220 or current 50 HZ / s use. While in many countries including UK, Europe, Australia, the voltage is 110–120 or current 60 HZ/s. voltage and current are inversely proportional, if current increase and all factors are consistent, the voltage will decrease.

### What is power?

Power watt is the multiplication of current and voltage (Amp× Volt)

example  if one motor use to run 2 amp current and 220 volt then it consume 2 × 220= 440 Watt Power.

If motor is 3 phase,then formula =   Amp × volt × (1.732/√3)
