Detailed explanation-1: -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.
Detailed explanation-2: -Voltage is the measure of energy available to move electrons. It requires a gradient (more energy on one side than the other) and a conductor.
Detailed explanation-3: -A resistor is a section of wire that resists the smooth flow of electrons.
Detailed explanation-4: -Resistance is the property of any material that slows down the flow of electrons. It converts electrical energy into other forms of energy. As the resistance of a material increases the amount of electrical energy converted into other form of energy increases.
