Question

what is resistance of current ​

Answer 1

Answer:

Resistance is the opposition that a substance offers to the flow of electric current. ... When an electric current of one ampere passes through a component across which a potential difference (voltage) of one volt exists, then the resistance of that component is one ohm.

Answer 2

• Resistance is a measure of the opposition to current flow in an electrical circuit.
• It is measured in Ohms.

Conductors show less resistance because electrons can move easily. Example -- silver, copper, gold and aluminum.

Insulators show high resistance because they restrict the flow of electrons. Example -- Rubber, paper, glass, wood and plastic.

Resistance is measured in two ways -----

         constant current or constant voltage
