Introduction I am going to do an experiment to find out that if you change the length the electric wire then what would happen if the resistant would increase or decrease. Scientific knowledge I am going to give the meaning of the following words so I can understand what they mean and there function. Resistance - Property of an electric conductor by which it opposes a flow of electricity and dissipates electrical energy away from the circuit, usually as heat. Optimum resistance is provided by a conductor that is long, small in cross section, and of a material that conducts poorly. Resistance is basically the same for alternating and direct current circuits. However, an alternating current of high frequency tends to travel near the surface of a conductor. Since such a current uses less of the available cross section of the conductor than a direct current, it meets with more resistance than a direct current. In circuit analysis an ideal resistor , i.e., a circuit component whose only property is resistance, is called a resistance.
