Study Guide
Troubleshooting a short circuit - The process of identifying and fixing a circuit with a direct
connection between the power source and ground.
Ground - The connection of an electrical circuit to the Earth.
Types of electrical current - Direct current (DC) and alternating current (AC).
Circuit tester - A device used to test the presence of voltage in an electrical circuit.
Components of an electrical circuit - Power source, load, conductor, and control device.
Types of power supplies - DC power supply and AC power supply.
Schematic symbols - Visual representations of electrical components used in electrical schematics.
Electrical output devices - Lamp, motor, solenoid, buzzer, and relay.
Voltage - The electrical potential difference between two points in a circuit. Unit of measurement:
volts (V).
Voltmeter - A device used to measure voltage in an electrical circuit.
, Voltage characteristics in series and parallel circuits - In series circuits, voltage adds up. In parallel
circuits, voltage is the same across all components.
Current - The flow of electric charge in a circuit. Unit of measurement: amperes (A).
Ammeter - A device used to measure current in an electrical circuit.
Current characteristics in series and parallel circuits - In series circuits, current is the same across
all components. In parallel circuits, current adds up.
Ohmmeter - A device used to measure resistance in an electrical circuit.
Continuity - The uninterrupted flow of current in an electrical circuit.
Metric prefixes used on DMM - Mega (M), kilo (K), milli (m), micro (μ).
Digital multimeter (DMM) - A device used to measure voltage, current, and resistance in an
electrical circuit.
Basic electrical units of measurement - Volt (V), ampere (A), ohm (Ω).
Series and parallel resistance - The calculation of total resistance in series and parallel circuits.
Ohm's Law - A mathematical equation relating voltage, current, and resistance in an electrical
circuit.
Kirchhoff's Voltage Law - The sum of voltage drops in a series circuit is equal to the applied
voltage.
