ASE A6 - Electrical Practice Test Questions with Correct Answers

1. When using a DMM (Digital Multimeter) voltmeter function to check for a voltage drop, meter leads should be connected in which of the following ways? a. On the "positive" side of the circuit b. Across the component or circuit c. To any non-conductive material d. In series with the circuit b. Across the component or circuit Voltage is always checked in parallel or across the device or circuit. 2. Which of the following is correct regarding a series circuit? a. Highest resistance has most current b. Lowest resistance has most current c. Lowest resistance has highest voltage drop d. Highest resistance has highest voltage drop d. Highest resistance has highest voltage drop Based on Kirchhoff's Voltage Law: Voltage higher before resistance than after, which is the result of total applied voltage not equal at both ends of a single load circuit. Resistance in circuit opposes electron flow with resulting voltage loss applied to load. The Loss is voltage drop with the voltage lost/consumed as current moves through resistance. HIGHER Resistance, HIGHER DROP. 3. When a Digital Multimeter (DMM) is used to measure DC voltage and is connected in parallel to the load device, which of the following defines the reading? a. Amperage reading b. Voltage drop c. Voltage spike d. Pulse width modulation b. Voltage drop Based on Kirchhoff's Voltage Law: Sum of voltage drops in any circuit will equal source VOLTAGE or VOLTAGE applied to circuit. 4. Which of the following tools can be used to check the continuity of wires that carry digital signals? a. Megger Meter b. Analog meter c. Logic probe d. Voltmeter c. Logic probe A logic probe is the only device that measures digital signals. 5. Using a DMM (Digital Multimeter), a fully charged 12 volt battery should indicate how much voltage on the open circuit voltage (OCV) test? a. 9.6 volts b. 4 volts per cell c. 1 volt per cell d. 12.6 volts d. 12.6 volts
