When electrons move through a conductor, such a metal wire, an electric current occurs. The ions in the metal may clash with the travelling electrons. Resistance is created as a result, making it more difficult for the current to flow. Resistance of medium depends on the ability of flow of particles present in the medium. If they are able to flow in the given direction then resistance decreases but if the velocity of particles are directed in different direction then they increase resistance.
Given
'The resistance of the medium increases as the velocity of the particle increases.'
Find
The given sentence is true or false.
Solution
If direction of particles are same and velocity of particles increases then resistance of medium decreases. Hence the given statement 'The resistance of the medium increases as the velocity of the particle increases.' is false.
Hence, the given statement is false.
