Circuit - correct answer A path in witch electricity flows. A closed circuit means a complete path. A open circuit means a interrupted path Current - correct answer Is the flow of electrons around the Circuit From a point of high potential to a point of low potential Direct Current - correct answer The flow of electrons in one direction, from the negative terminal to the positive terminal. The higher the voltage, the more electrons available Alternating Current - correct answer The flow of electrons periodically changes directions Resistance - correct answer Is measured in ohms. Everything has some resistance, the more resistance, the slower the flow of electricity Conductor - correct answer Materiel in witch an electrical current can flow with little to no resistance Insulator - correct answer Material that resists a electric current Semiconductor - correct answer is a material that has conductivity partway between a conductor and an insulator with the primary advantage of showing increased conductivity with increased temperature unlike conductors where conductivity decreases with increased temperature. A set relationship exists between voltage (V), resistance (R), and current (I) in an electrical circuit: - correct answer current is voltage ÷ resistance: I = V / R Resistance voltage ÷ current: R = V / I Voltage is resistance x current: V = I x R Power Consumption - correct answer One watt equals one ampere multiplied by one volt or P = V x I. Batteries - correct answer the most common DC power source and the most common types of batteries are dry cell (AA, C, D, etc.), wet cell (used in cars), and storage (backup and emergency batteries). Photo voltaic - correct answer convert energy from the sun into batteries Electrical wiring - correct answer used to connect circuits and equipment. coaxial cable - correct answer another type of electrical wiring, except it transmits radio frequency Capacitor - correct answer stores an electrical charge using two parallel plates A Switch - correct answer A device for opening and closing an electrical circuit Electromagnets - correct answer artificial magnets that are made by passing electrical current through a coil of wire wrapped around an iron core Inductor - correct answer stores energy in form of a magnetic field. Transformer - correct answer turns ac voltage to a higher or lower potential rectifier - correct answer converts ac voltage to dc voltage Diode - correct answer A semiconductor that only allows an electrical current in one direction inverter - correct answer converts dc voltage to AC voltage Thermocouple - correct answer A temperature sensitive switch that will open or close a circuit based on temperature
