The standard metric unit for resistance is the ohm, represented by the Greek letter omega - . Some materials are better conductors than others and offer less resistance to the flow of charge. Not all materials are created equal in terms of their conductive ability. Let’s take a look!

Just as all materials have a certain specific resistance (at 20° C), they also change resistance according to temperature by certain amounts. After reading the text below you will, for example, learn how you can estimate the resistance of a wire using the resistance formula (so-called Pouillet's Law).

What are the different types of Resistors? You can buy different rating of resistor as per your requirement.

For a given material, the resistance is inversely proportional to the cross-sectional area; for example, a thick copper wire has lower resistance than an otherwise-identical thin copper wire. We use cookies to provide you with a great experience and to help our website run effectively. Copper and aluminum are among the least expensive materials with suitable conducting ability to permit their use in wires of household circuits. An easier way to explain resistance is to consider an example of a person in a crowded market struggling to go from one shop to another. Consistent with the discussion above, this equation shows that the resistance of a wire is directly proportional to the length of the wire and inversely proportional to the cross-sectional area of the wire. Unit: It SI unit and CGS Unit are Ohm (represented by ‘Ω‘). Georg Simon Ohm expressed his discovery in the form of a simple ohm’s law equation that describes how voltage, current, and resistance interrelate: In this ohms law equation – voltage (V) is equal to the current (I) multiplied by resistance (R).

Both conductance and resistance depend on the geometrical dimensions of a wire.

Resistance. After all, if resistance occurs as the result of collisions between charge carriers and the atoms of the wire, then there is likely to be more collisions in a longer wire. It could overheat and thus lead to the risk of fire. Sharing my knowledge on this blog makes me happy. Trajectory - Horizontally Launched Projectiles Questions, Vectors - Motion and Forces in Two Dimensions, Circular, Satellite, and Rotational Motion. If wire A has four times the resistance, then it must have the smaller cross-sectional area since resistance and cross-sectional area are inversely proportional. Electric current refers to the flow of electrons. And insulators usually have more resistance and good conductors have low resistance.
