What is resistance ?

Question

Accepted Answer

Resistance is the measure of opposition to the flow of electric current in a material.

Resistance is measured in ohms (Ω).
It is caused by the collisions of electrons with atoms and other electrons in the material.
Resistance can be influenced by factors such as temperature, length, and cross-sectional area of the material.
Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage applied and inversely proportional to the resistance.
For example, a thin wire has higher resistance compared to a thick wire of the same material and length.

What is resistance?
Resistance is a measure of the opposition to current flow in an electrical circuit.

Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current and resistance. He is credited for formulating Ohm's Law.

All materials resist current flow to some degree. They fall into one of two broad categories:

Conductors: Materials that offer very little resistance where electrons can move easily. Examples: silver, copper, gold and aluminum.
Insulators: Materials that present high resistance and restrict the flow of electrons. Examples: Rubber, paper, glass, wood and plastic.
