Digital Electronics PLTW Questions and Correct Answers & Latest Updated

Voltage (V) o :## The difference in electrical potential energy between two places in a circuit. Current (I) o :## A flow of electric charge. Resistance (R) o :## the opposition of current flow (measured in Ohms) Ohm's Law o :## The current in a circuit equals the voltage difference divided by the resistance Series Circuit o :## A circuit in which all parts are connected end to end to provide a single path of current. Parallel Circuit o :## A 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 2 | P a g e Exams and Correct Answers |Best Grades | Excellence | Success o :## The algebraic sum of all voltages around any closed path must equal zero. Kirchoff's Current Law o :## The current that goes into a branch is equal to the current that comes out of a branch. Discrete Components o :## The most basic electronic units that can be incorporated into a circuit. Small-Scale Integration (SSI) o :## An integrated circuit having 12 or fewer gates in one package. Medium Scale Integration (MSI) o :## An IC that contains circuitry equivalent to more than 11 and less than 100 gates. INVERTER gate o :## Also called a NOT gate or an inverting buffer. A logic gate that changes its input logic level to the opposite state. AND Gate o :## A logic gate that takes in 2 inputs and only outputs True if both inputs are True. NAND Gate 3 | P a g e Exams and Correct Answers |Best Grades | Excellence | Success o :## Logic circuit that operates like an AND gate followed by an INVERTER. The output of a NAND gate is LOW (logic level 0) only if all inputs are HIGH (logic level 1). OR Gate o :## A circuit with two inputs and one output defined such that its output is TRUE (or ON) when either or both of its inputs are TRUE (or ON). NOR Gate o :## Logic circuit that operates like an OR gate followed by an INVERTER. The output of a NOR
