Why a copper wire is well covered by the insulating plastic material?
Electricity is very dangerous and can kill. Perhaps the most important reason why electrical wires are covered in plastic is to protect people from electrical shock. Covering electrical wires in plastic guarantees that the electrons flowing through the wires will not flow through your body when the wire is touched.
What is the reason for using an insulated wire in making armature?
The copper wire around an electromagnet is insulated to avoid current flow between the wires. If the wire is uninsulated the current will take a short cut and will not flow multiple times around the core. If the current does not flow as a loop then the magnetic field will not be created.
Why do we use insulated copper wire in electric motor?
Originally Answered: Why should we use insulated copper wire in electric motor? Because if uninsulated wire is wound as densely as needed it would short out the windings. Usually the wire is insulated with some form of varnish or similas material to allow very close windings.
Why do current carrying wires have multiple thin copper wires instead of a single thick copper wire?
Copper being a very good conductor of electricity is used extensively in electric wires and cables. Hence, instead of single copper strand, a copper wire has numerous multi-strands that increases its circumference dimension so that for the same amount of the copper, a wire of higher rated current can be manufactured.
Why do we cover the electric wires with plastic or rubber?
Covering electrical wiring using plastic ensures that the current doesn’t flow outside the system. This avoids shocks, short-circuit etc. Plastics are non-reactive and poor conductors of electricity or to be precise, they are insulators. They do not allow the electric current to pass through them easily.
Why do you use insulated wire in an electromagnet?
Because without insulation the electricity will take the shortest, lowest-resistance course, which will be laterally across windings. It will not flow multiple times around the core, which is what produces the magnetic flux that is the whole point of an electromagnet.
Why copper is used in armature?
Copper wires are very commonly utilized in the method of supplying electricity as they need a high level of conductivity. It’s highly ductile which suggests it are often drawn and stretched into wires. Copper features a high thermal and electrical conductivity.
Why should we use thin wires for DC circuits?
DC requires a larger wire to carry a larger current – and due to resistance, it heats up more. Using a higher voltage would reduce the current… but DC voltage converters are rather expensive, and more easily damaged.
Why do we use multi strand wire?
Multi-strand wiring is more flexible and less susceptible to cracking and metal fatigue than single stranded conductors. The increased surface area of multi-stranded conductors decreases the amount of resistance that currents or signal passing through the wire will encounter.
Why is it important that the outer covering of the plug is made from plastic?
Covering electrical wiring using plastic ensures that the current doesn’t flow outside the system. This avoids shocks, short-circuit etc. Complete step by step answer Electrical wires are covered with a layer of plastic to make it safe.
