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.
