what is resitance

Resistance:

Resistance:it is which opposes of the current is nothing but resistance.

 A measure of how difficult it is for the energy to flow
Toasters use resistance to toast bread often associated with voltage and current is resistance.

Resistance is how much the electricity is
being held back, or how difficult it is for electricity to flow though part of a circuit.

 Resistance is measured in ohms.

Different materials have different levels of resistance. Remember
the difference between conductors and insulators?

Copper and aluminum wires have a very low resistance to the flow
of electrical current. That is why they are conductors of electricity.
The plastic around a copper wire has a very high level of resistance.
That is why it is an insulator. Plastic will not allow electricity to
easily flow through it.

Toasters work on resistance. When electric current passes through
the wires of a toaster, the resistance causes the wires to heat up,
toasting your bread.
