Voltage ⚡ Current , Power , ohm's law

 • Voltage : 

The potential difference across two terminals in a circuit is known as Voltage.

            Denoted by 'v'

            Units by 'volts'

            Measured by 'voltmeter'

Therefore, Simply Voltage = flow of pressure.

 • Current : 

The flow of electrons from one terminal to another terminal through a conductor in a circuit is known as Current.

             Denoted by 'A'

             Units by 'Amp'

             Measured by 'Ammeter'

 • Power : 

It's is the product of voltage and current combination.

               Denoted by 'P'

               Units by 'watts'

               Measured by 'Wattmeter'

• Resistor :

It's is a device which is use to resist or appose the flow of current.

              Denoted by 'R'

              Units  by (Ω)

 • Capacitor : 

Which store the energy in the form of voltage. It's stop sudden change in voltage

               Denoted by 'c'

               Units by 'Farads'

 • Inductor :

Which store the energy in the form of current. It's stop sudden change in current.

                Denoted by 'L'

                Units by 'henry'

 • Phase Angle Difference :

The difference between the starting point of wave from voltage & current is known as Phase Angle Difference.

Resistor → Both current and voltage are same.

Capacitor → Current lag and Voltage lead.

Inductor → Voltage lag and Current lead.

 • Types of power :

Active power - watts.

Reactive power - KVAR.

Apparant power - KVA.

 • OHM'S law :
