Definitions and Examples:
1.
AC (Alternating Current): Electric
current that reverses direction periodically.
Example: Chinedu’s home is powered by ac, which makes his appliances
function efficiently.
2.
Adapter: A device that allows
electronic devices to connect with different types of sockets or ports.
Example: Nneka used an adapter to plug her laptop into the hotel's
electrical outlet.
3.
Alternator: A generator that produces
alternating current.
Example: The alternator in Emeka’s car helps keep the battery charged while
driving.
4.
Ampere: The unit of electric current.
Example: The circuit in Ada’s new house is designed to handle up to 20
amperes of current.
5.
Battery: A device that stores and
provides electrical energy.
Example: The battery in Tunde's torch lasted all night during the power
outage.
6.
Breaker: A switch that automatically
interrupts the electrical circuit to prevent overloads.
Example: When the oven short-circuited, the breaker tripped and shut off
the power.
7.
Cable: A bundle of wires used to
transmit electricity or data.
Example: The electrician ran a new cable to connect the house to the main
power supply.
8.
Capacitor: A device that stores
electrical energy temporarily.
Example: The capacitor in the air conditioner helps to stabilise the
voltage supply.
9.
Circuit: A complete path through which
electric current can flow.
Example: The electrician traced the faulty circuit to find the source of
the problem.
10. Conduit:
A tube used to protect and route electrical wires.
Example: The wires were routed through a metal conduit to prevent damage.
11. Connector:
A device used to join electrical wires.
Example: The connectors in the junction box were crucial for maintaining a
stable connection.
12. Current:
The flow of electric charge.
Example: The current through the wires was too high, causing the fuse to
blow.
13. DC
(Direct Current): Electric current that flows in one direction only.
Example: The batteries in Ifeoma’s remote control provide direct current
for its operation.
14. Distribution:
The process of delivering electrical power to various locations.
Example: The electrical distribution system in Lagos ensures power reaches
every household.
15. Electrician:
A person who installs and maintains electrical systems.
Example: The electrician, Mr. Oladipo, fixed the wiring issue in my office.
16. Fuse:
A safety device that melts to protect the circuit from excessive current.
Example: The fuse blew when the power surge occurred, preventing further
damage.
17. Generator:
A machine that converts mechanical energy into electrical energy.
Example: The generator provided power during the blackout at Chuka’s event.
18. Grounding:
The process of connecting the electrical system to the earth to prevent
electric shock.
Example: Proper grounding of the electrical system helped to ensure safety
in the building.
19. Harmonic:
A frequency component of the signal that is an integer multiple of the
fundamental frequency.
Example: Harmonics in the electrical system can cause inefficiencies in power
distribution.
20. Hub:
A central point where multiple electrical connections are made.
Example: The networking hub in the server room managed all data connections
effectively.
21. Insulator:
A material that resists the flow of electricity.
Example: The insulator on the power lines prevented accidental contact and
electric shocks.
22. Junction:
A place where two or more electrical wires meet.
Example: The junction box housed all the connections for the lighting
system.
23. Kilowatt:
A unit of power equal to 1,000 watts.
Example: The new generator has a capacity of 5 kilowatts, sufficient for
the entire house.
24. Load:
The amount of electrical power consumed by a device or system.
Example: The electrical load on the circuit increased when the air
conditioner was turned on.
25. Meter:
A device used to measure electrical usage.
Example: The electric meter in Amina’s house recorded her power consumption
for the month.
26. Neutral:
A wire that carries current back to the power source and is grounded.
Example: The neutral wire is essential for completing the electrical
circuit in the house.
27. Outlet:
A socket where electrical devices are plugged in.
Example: The new outlets installed in the kitchen have USB ports for
convenience.
28. Panel:
The main distribution board that houses circuit breakers or fuses.
Example: The panel in Emmanuel’s house needed an upgrade to accommodate new
circuits.
29. Power:
The rate at which electrical energy is transferred or used.
Example: The power requirement for the new machines exceeded the building’s
capacity.
30. Relay:
An electrically operated switch used to control a circuit.
Example: The relay in the control panel allows automatic switching between
power sources.
31. Receptacle:
A device that allows the connection of electrical appliances.
Example: The receptacle in the living room was designed to handle
heavy-duty appliances.
32. Regulator:
A device that controls voltage levels to protect electrical equipment.
Example: The voltage regulator ensured the TV received a steady and safe
voltage supply.
33. Resistance:
The opposition to the flow of electric current.
Example: The high resistance in the old wiring caused the lights to
flicker.
34. Socket:
A fitting that allows electrical plugs to be inserted and connected.
Example: The socket in the study room was upgraded to accommodate new
devices.
35. Switch:
A device used to open or close an electrical circuit.
Example: The light switch in the hallway was replaced with a more modern
design.
36. Transformer:
A device that changes the voltage of an electrical supply.
Example: The transformer steps down the high voltage from the power lines
to a safer level.
37. Voltage:
The electric potential difference between two points.
Example: The voltage drop in the wiring caused the appliances to
underperform.
