wiring is a typical electrical application of copper.
than silver copper is the best electrical conductor. Another thing is that it
has good thermal conductivity, this is good because it means it has a high
melting point which is important. its malleability also makes it good for wires
as it can be easily shaped without breaking. Also, its ductility makes it perfect
for wires as it can be stretched very thin without compromising the strength of
common application of mercury is a mercury switch. This is a electrical switch
that opens and closes a circuit when mercury connects metal electrodes.
is used in switches for a few reasons. Firstly, when using mercury interrupting
a circuit does not cause a spark this is good because in hazardous situations a
spark could ignite flammable gases. Secondly
that contacts stay clean, even if an internal arc occurs the contact surfaces
renew on every operation meaning that it doesn’t wear out
common use of PVC is the insulation sheathing of electrical cables
is good for sheathing for many reasons. Firstly, it is a non-conductor, this is
good for sheathing because it will not conduct the electricity going through
the wire. Secondly it can be cut, shaped and joined easily. It also has good
dielectric strength which is good for sheathing because it can take a high
voltage before dielectric breakdown.
common use of transformer oil is oil filled transformers
oil has very good dielectric strength, this is good because it means minimal
amount of power is lost. It also has high resistivity, which provides better
insulating values between the windings, it also has good thermal stability provides
a reduction in evaporation loss.
