Electrical Resistance **Definitions** [Resistance]: The ability to \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ in conductors. [Resistors]: Anything that provides \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ in a circuit is called a It is an electrical device designed to provide resistance. [ELECTRICAL RESISTANCE] In a good conductor, electrons \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ as they travel. In other materials, the energy of the atoms is converted to \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_, which results in a \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_(voltage). Electricity is converted into \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ when it meets resistance. The four types of energy are: 1. 2. 3. 4. THERE ARE FOUR FACTORS THAT AFFECT ELECTRICAL RESISTANCE 1. **\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_** When electricity travels through some types of materials, the \_\_\_\_\_\_\_\_\_\_\_\_\_ move and vibrate. This causes the wire to \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ and some of the electrical energy is lost to thermal energy. 2. **\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_** The \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ the wire, the more electrical resistance the wire has. Electrons flowing through a long wire have more material to go through and have a greater chance of making the \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_. 3**. \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_** A \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ wire had less electrical resistance than a thin wire. A thick wire is like a multi-lane highway and gives the electrons \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ to travel through. 4. **\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_** When the temperature of a material \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_, the electrical resistance will increase. When the wire warms up, the atoms will \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_, which increases the chance that the electrons will collide with the moving atoms in the material.
