What will let electricity flow through it

The higher the resistance, the lower the flow of electrons. This resistance causes a certain amount of heat to be generated in the circuit. The reason that a hairdryer blows hot air, for example, is because of resistance in the internal wiring, which produces heat. And it is resistance in the tiny wires of an incandescent light bulb that causes it to heat up and glow with light.

It is also resistance that can overheat an extension cord if it is used on an appliance that draws too much current. In circuit wiring, too much resistance can overload a circuit and cause an electrical fire. Because bad connections caused by things like loose screw terminals and corrosion are likely culprits, electrical connections should be checked regularly to ensure safety in an electrical system.

If you have any concerns about your electric work or want to be proactive about safety, consider hiring a professional to do a routine check. Actively scan device characteristics for identification.

The symbol is R The unit of resistance is the ohm W Good wires have low resistance The resistance of a wire depends on its length, thickness and temperature. Thinner wires have greater resistance than thick wires Longer wires have greater resistance than shorter wires Hotter wires have greater resistance due to the increased KE friction within the wire.

Superconductors often are kept at very low temperatures where the resistance becomes near zero. States that the current is equal to the voltage divided by the resistance.

A problem on dairy farms is "stay voltage," caused by corroded wiring, poor wiring practicies, or ground currents associated with nearby power lines.

These conditions can result in several volts of potential difference between metal objects such as watering bowls, feed troughs, or milking equipment, and the ground. Cows feel slight shocks that make them nervous, resulting in reduced milk output. As a result, farmers can face serious financial losses.
