flow - movement in a steady and uninterrupted way, alternating current (AC) - an electric current that reverses direction in a circuit at regular intervals, ammeter - a device that measures the current in amperes, ampere (amp) - the unit of measurement of electric current, amplitude - the maximum strength of alternating current or voltage above or below an average, branch - a path through which current can flow in a circuit, break loose - to become separated from, conductor - a category of elements whose atomic structure presents minimal resistance to current flow, direct current (DC) - electric current that flows in one direction only, commonly found in low-voltage applications, fuse - a component used to protect a circuit by interrupting, impeding, or stopping the flow of excessive current, insulate - to apply a material to (something) in order to stop electricity, heat, or sound from going into or out of it, insulation - material that is used to stop electricity, heat, or sound from going into or out of something, insulator - a category of elements whose atomic structure presents a high resistance to electrical current flow, load - any electrical component that consumes power, ohm - the unit of measurement of resistance, Ohm’s Law - a law of physics that states that the current in a circuit is directly proportional to the applied voltage and inversely proportional to the circuit resistance: Voltage = Current x Resistance: (V = I x R), parallel circuit - a circuit that contains two or more branches sharing the same applied voltage, but with separate currents, path - a route along which something moves, power supply - a device that provides electrical power to a machine, rectifier - a device that converts AC into DC, resistance - obstruction to a flow of electric current through a circuit, resistor - an electronic component that resists the flow of current and produces a voltage drop that is proportional to the current passing through it, semiconductor - a category of elements that falls between conductors and insulators, series circuit - a closed circuit with only one path for current flow, step down - to decrease voltage and increase alternating current across a transformer, step up - to increase voltage and decrease alternating current across a transformer, switch - a device that permits control of an electrical circuit by interrupting the current delivered to the load, to flow - to move in a steady and uninterrupted way, transformer - a device used to increase (step up) or decrease (step down) voltage or current within a circuit, volt - the unit of measurement of voltage,
