GEOLOGY

Detailed explanation-1: -Resistance. Electrical Resistance measures how easy or difficult it is for electrons to move through a material, under the influence of voltage.

Detailed explanation-2: -The resistance of an electric circuit is a measure of the overall amount of hindrance to the flow of charge through the circuit. A large resistance value indicates that the charge is encountering a relatively large amount of difficulty in moving through the circuit. The unit of resistance is the ampere.

Detailed explanation-3: -Since conductivity is the measure of how easily electricity flows, electrical resistivity measures how much a material resists the flow of electricity.

Detailed explanation-4: -The unit of measurement for resistance is ohms and its symbol is the Greek letter omega (). The resistance of one ohm means a conductor allows a current of one amp to flow with a voltage of one volt. All materials are difference in allowing electrons flow.

Detailed explanation-5: -An ampere (AM-pir), or amp, is the international unit used for measuring current. It expresses the quantity of electrons (sometimes called “electrical charge") flowing past a point in a circuit over a given time.
