Components of an electrical circuit - โโโ Correct Answer > Power source, load, conductor, and control device. Schematic symbols - โโโ Correct Answer > Visual representations of electrical components used in electrical schematics. Voltage - โโโ Correct Answer > The electrical potential difference between two points in a circuit. Unit of measurement: volts (V).
Current characteristics in series and parallel circuits - โโโ Correct Answer > In series circuits, current is the same across all components. In parallel circuits, current adds up. Ground - โโโ Correct Answer > The connection of an electrical circuit to the Earth. Ten rules of electrical safety - โโโ Correct Answer > A set of guidelines to ensure safe practices when working with electricity. Lockout / tag out - โโโ Correct Answer > A safety procedure used to disable machinery or equipment to prevent hazardous energy release.
Ohmmeter - โโโ Correct Answer > A device used to measure resistance in an electrical circuit. Resistance characteristics in series and parallel circuits - โโโ Correct Answer > In series circuits, resistance adds up. In parallel circuits, the total resistance is less than the smallest resistance. Continuity - โโโ Correct Answer > The uninterrupted flow of current in an electrical circuit. Metric prefixes used on DMM - โโโ Correct Answer > Mega (M), kilo (K), milli (m), micro (ฮผ).
Series and parallel voltage - โโโ Correct Answer > In a series circuit, the current flows through all the components in the same path. As a result, the total voltage across the circuit is equal to the sum of the voltages across each of the components. In a parallel circuit, the current can flow through multiple paths. As a result, the voltage across each of the components in a parallel circuit is the same. The total current in the circuit is equal to the sum of the currents through each of the components.
