Magnetic Ballast

           An electrical ballast is a device intended to limit the amount of current in an electric circuit. A familiar and widely used example is the inductive ballast used in alternating current fluorescent lamps, to limit the current through the tube, which would otherwise rise to destructive levels due to the negative differential resistance artifact in the tube's voltage-current characteristic.

     In below i give you a link where you can get information about types of magnetic ballast.

What's inside an Electrical Starter use to start tube light

           Inside a electrical starter there is basically two things are present one is capacitor another is a bi-metallic strep. This bi-metallic strip is normally in closed condition but when current passes through it due to heat loss this strip is going to increase it's length, and as a result the circuit is going to disconnected.

Actually starter works with choke coil, to release photon from tube light it is required to ionized the tube gas and for starting stage it requires high voltage, now concept E= L*di/dt when rate of change of current is high then emf will be high, so starter works very fast and when the voltage reaches at required limit to start the tube then starter out from circuit of tube light electrically.

 

 

My next video will describe the inner parts of a electrical choke or ballast.

ARDUINO UNO demonstration

ARDUINO UNO is basically a micro controller board which is use to code a micro processor i.e, AT Mega 328P .In left hand side you see an ARDUINO UNO board.In here you see there is 14 digital  input output pins(0 to 13) & there is 6 analog input pins available ( A0 to A5).There is some basic details available which i am describe in my video. So, please see this video.
