Digital Electronics PLTW Exam Study Guide.

Digital Electronics PLTW Exam Study Guide. Voltage (V) - answerThe difference in electrical potential energy between two places in a circuit. Current (I) - answerA flow of electric charge. Resistance (R) - answerthe opposition of current flow (measured in Ohms) Ohm's Law - answerThe current in a circuit equals the voltage difference divided by the resistance Series Circuit - answerA circuit in which all parts are connected end to end to provide a single path of current. Parallel Circuit - answerA closed electrical circuit in which the current is divided into two or more paths and then returns via a common path to complete the circuit. Kirchoff's Voltage Rule - answerThe algebraic sum of all voltages around any closed path must equal zero. Kirchoff's Current Law - answerThe current that goes into a branch is equal to the current that comes out of a branch. Discrete Components - answerThe most basic electronic units that can be incorporated into a circuit. Small-Scale Integration (SSI) - answerAn integrated circuit having 12 or fewer gates in one package. Medium Scale Integration (MSI) - answerAn IC that contains circuitry equivalent to more than 11 and less than 100 gates. INVERTER gate - answerAlso called a NOT gate or an inverting buffer. A logic gate that changes its input logic level to the opposite state. AND Gate - answerA logic gate that takes in 2 inputs and only outputs True if both inputs are True.
