Electrical Level 2 Module 10 Questions
and Answers | Latest Version | 2024/2025
| 100% Pass
How does a switch control the flow of electricity?
✔✔A switch opens or closes a circuit, allowing or preventing the flow of electrical current to
connected devices.
What is the difference between a series and parallel circuit?
✔✔In a series circuit, components are connected end-to-end, and the current flows through each
component in sequence. In a parallel circuit, components are connected across common points,
allowing current to flow through multiple paths.
What is the purpose of a transformer in an electrical system?
✔✔A transformer changes the voltage level of electricity, either stepping it up for transmission
or stepping it down for use in homes and businesses.
Why is it important to use the correct wire size in a circuit?
✔✔Using the correct wire size ensures that the wire can safely carry the intended current without
overheating or causing a fire hazard.

, What is an overload condition in an electrical system?
✔✔An overload occurs when more current is drawn through a circuit than it is designed to
handle, which can cause overheating or damage to the circuit and connected devices.
What does a multimeter measure in an electrical circuit?
✔✔A multimeter measures various electrical properties such as voltage, current, and resistance,
allowing for diagnostic and troubleshooting of circuits.
Why is it necessary to use an insulated wire in electrical installations?
✔✔Insulated wire prevents accidental contact with live wires, protecting users from electrical
shock and preventing short circuits.
What is the function of a relay in an electrical circuit?
✔✔A relay is an electrically operated switch that uses a small current to control a larger current,
enabling remote control or automation of devices.
What does the term "voltage drop" mean in an electrical circuit?
