Detailed explanation-1: -i.e. resistance is defined as the property of conductor due to which it opposes the flow of electric current through it.

Detailed explanation-2: -Electrical. 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 (). Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current and resistance.

Detailed explanation-3: -Current is the rate at which charge is flowing. Resistance is a material’s tendency to resist the flow of charge (current).

Detailed explanation-4: -Electricity is generated due to the continuous flow of free electrons. To control the free flow of current a hurdle is required in order to prevent the electric appliance from getting damaged. This hurdle or the opposition to the flow of charges is termed resistance.

Detailed explanation-5: -The resistance of a conductor is defined as the ratio of the potential difference across its end to the current flowing through it. Its SI unit is ohm ().
