NCCER Electrical Level Module 3 exam 2023 with 100% correct answers

Define Voltage? - correct answer -The driving force that makes current flow in a circuit. Voltage often represented by the letter E, is also referred to as electromotive force (emf), difference of potential, or electrical pressure. Define Current? - correct answer -The movement, or flow, of electrons in a circuit. Current(I) is measured in amperes. Define Resistance? - correct answer -An electrical property that opposes the flow of current through a circuit. Resistance (R) is measured in ohms. Define Watts? - correct answer -The unit of measurement for electrical power, represented by the letter W. Define Amperes? - correct answer -The basic unit of measurement for electrical current, represented by the letter A. What is a Coulomb? - correct answer -A unit of electrical charge equal to 6.25x10^18 electrons (or 6.25 quintillion electrons.) A coulomb is the common unit of quantity used for specifying the size of a given charge. What is an Ammeter? - correct answer -An instrument for measuring electrical current. What is an Ohmmeter? - correct answer -An instrument used for measuring resistance What is an Voltmeter? - correct answer -An instrument for measuring voltage. The resistance of the voltmeter is fixed. When the voltmeter is connected to a circuit, the current passing through the meter will be directly proportional to the voltage at the connection points.
