How Electric Train works in a single wire - Explain

 Electric Train works in a single wire

Usually, Electronic Devices are work in Two-wire that are Phase and Neutral. The current flow in the phase wire and return back through the neutral wire. If the neutral wire is absent, the current cannot return so the devices don't work. This is called Open Circuit. Now let us see how Electric Train works in a single wire. Is there any magic? No!. Before we discuss this topic. We should discuss the related fact of how Electric Tester is working. Because these two things are working on the same principle.

                                                                

                                                              

How Electric Tester working :

                                                                         Tester having One resistor of 10L ohm, one neon bulb, and then spring. Okay, let us see how this works. When the tip of the tester is inserted into a hole in the electric socket. The current of 230V passes into the conductor and it reaches the resistor. Resistors are used to reduce the amplification of current. In this device, 230V is reduced to 0.23Amp of current and this current then goes to the neon bulb. So far the current (phase) flows on it. So the neon bulb couldn't glow. When the body touches the terminal of the tester the current flows on the body of conductance and reaches the ground and the circuit is closed neon bulb will glow. Now you think about the 230v of current can attack humans? Definitely not. Because there is a resistor to reduce the high current into very low.

Tester materials :

• Resistor (10L ohms)
• Neon Bulb
• Spring
• Metal Cap

                                                                 

Electric Train in Single Wire :

                                                                          So far we discussed how the electric tester working. Like that Electric Trains are having pantograph. A pantograph is an apparatus mounted on the top of the roof of an electric train to collect electric power through an overhead electric rod. The electric rod passes 21,000 volts of current.

                                                                   

                                                                 Pantograph touches the electric rod and the current passes through in it. The power reaches the electric engine of the train and it flows on the Transformer. The transformer provides the power to the rectifier to amplify the current back to the transformer. This power can be grounded by axle brush (Wheel of the Train) The circuit completed with Train Tracks. Now the circuit is closed. The phase current passes on the roof and the neutral current completes with Train Wheel.
