**IMAGING EQUIPMENT AND MAINTENANCE** **STUDENT'S HANDOUT** **[Electrification]** Whenever electrons are added to or removed from material, the material is said to be electrified. Electrification can occur by contact, friction, or induction. **Electrification by Contact:** occurs when an object having an excess number of electrons contacts a neutrally charged object or an object with a deficiency of electrons. **Electrification by Friction:** occurs when we rub two neutral bodies, there will be some transfer of electrons from one body to the other due to structural modifications because of the frictional forces acting on them. **Electrification by Induction:** occurs when a highly electrified object comes close to a neutral object so that the electrons are transferred by spark. **[Potential Difference]** **Electrical energy** represents the *work that can be done when an electron moves* through an **electric potential difference (voltage)**. The most familiar form of electrical energy is normal household electricity, which involves the movement of electrons through a copper wire by an electric potential difference of 110 volts (V). All electric apparatus, such as motors, heaters, and blowers, function through the use of electrical energy. - - **[CURRENT]** ***Electric Current/Electricity*** - - - - - ***Tube Current / X-ray Tube Current*** - **[Direct Current]** - - **[Indirect Current]** - - - - - **Rectification -** The Process of converting alternating current (AC) to direct current (DC). **Rectifier -** The device that can convert an alternating current (AC) to direct current (DC). **[RESISTANCE]** - - All materials resist current flow to some degree.
