What is Resistance  Explain Animation On video

Resistance is a measure of the opposition applied to current in an electrical circuit.

Resistance is measured in ohms, the unit of which is symbolized by the Greek letter omega (Ω). This unit refers to the German physicist Georg Simon Ohm (1784-1854) who studied the relationship between voltage, current and resistance. He discovered the law that bears his name, Ohm's law.

All materials offer resistance to current to some extent. They fall into two categories:

Conductors: materials that offer very little resistance and through which electrons can move easily. Examples: silver, copper, gold and aluminum.
Insulators: materials that offer high resistance and restrict the flow of electrons. Examples: rubber, paper, glass, wood and plastic.

Resistance measurements are normally taken to indicate the condition of a component or circuit.
