How ELECTRICITY works - working principle
The Engineering Mindset
Everything, including you, is made from atoms. The atoms are made from three particles,
two of which are inside the nucleus.. atoms which can pass electrons are called conductors
and most metals are conductors. On the other hand, atoms which do not have free electrons
and so they ca n't pass electrons between other atoms are called insulators.. A nine volt
battery can provide nine joules of energy in the form of work or heat per group of electrons
that flow from one side of the battery to the other. a volt is a joule per coulomb and a
coulomb is a group of flowing electrons. the more voltage you have, the more electrons can
flow in a circuit. the longer the wire which carries the electrons will naturally have some
resistance. The thicker the wire, the lower the resistance. electrical circuits use specially
designed components known as resistors too. purposely restrict the flow of electrons. This
is either to protect other components from too many electrons flowing through it or it can
also be used to create light and heat.. When a wire is wrapped in a coil, it will generate a
magnetic field as the current passes through it. and this is how electromagnets work and it 's
also the base of how induction motors work. we can increase the strength of the magnetic
field simply by wrapping the coils around an iron core..
A capacitor forces positive and negative charges to separate across two plates when it is
connected to a power supply.. This causes a buildup or store of electrons within an electric
field.. when the power supply is cut or interrupted, these charges will then be released, flow
up, and meet again.. This provides a power source but only for a few seconds until the
charges have paired back up again. I hope you enjoyed this and it helped you. if you have any
questions, please leave me in the comments section below.. also do n't forget to subscribe
and check out our website. recommend having a google or a Youtube of this, too. all right,
that 's it for this video.
