What is electricity?
What are the two main types of electricity?
Static Electricity: Accumulated charge without continuous flow.
Current Electricity: Continuous flow of electric charge, used in power systems.
Define voltage and current.
What is the difference between AC and DC power?
Alternating Current (AC): The direction of electron flow changes periodically.
Direct Current (DC): The electron flow remains in one direction.
What are some common applications of DC power?
Electric vehicles (EV batteries).
Telecommunications (energy-efficient power supplies).
Renewable energy systems (solar panels, fuel cells).
Consumer electronics (laptops, smartphones, LED TVs).
What are the advantages of AC power in transmission?
Easily converted to different voltages using transformers.
Lower power losses over long distances.
More suitable for household and industrial power distribution.
What are the common sources of power generation?
Fossil fuels (coal, oil, natural gas).
Nuclear energy (nuclear fission).
Renewable energy (solar, wind, hydro, geothermal).
What is a substation and its function?
Why is AC power preferred for power distribution?
What is a switchboard, and why is it important?
What is the purpose of a motor control center (MCC)?
What are the safety precautions for working with electrical systems?
Turn off the power before performing maintenance.
Use insulated tools.
Wear rubber gloves and safety shoes.
Avoid working in wet conditions.
What are the main types of lighting sources?
Natural lighting (daylighting): Uses sunlight to illuminate spaces.
Artificial lighting: Includes incandescent, fluorescent, LED, and HID lighting.
Why is daylighting important in building design?
What are the key considerations for daylight control?
What are the three main types of artificial lighting?
Incandescent lighting: Produces light by heating a tungsten filament.
Fluorescent lighting: Uses gas discharge to produce UV light, which excites a phosphor coating to emit visible light.
LED lighting: Uses semiconductors to generate light efficiently.
How is lighting intensity measured?
What is the difference between warm white and cool white light?
What factors should be considered in lighting design?
What are the three methods to reduce glare in interior lighting?
