What is the purpose of an electrical plan?

• To provide a color scheme for interior design.

• To specify the types of furniture in a room.

• The purpose of an electrical plan is to provide a detailed layout of electrical systems for safety and compliance.

• To outline the plumbing layout of a building.

Name three common symbols used in electrical layouts.

• Transformer

• Circuit Breaker

• Fuse Box

• Light Fixture, Outlet, Switch

What does a circuit diagram represent?

• A circuit diagram represents the colors used in a painting.

• A circuit diagram shows the flow of water in pipes.

• A circuit diagram represents the electrical connections and components in a circuit.

• A circuit diagram illustrates the layout of a building.

Identify the basic components of a lighting circuit.

• Power source, switch, light fixture, wiring

What is the standard voltage for residential electrical systems?

• 110 volts

• 240 volts

• 100 volts

• 120 volts (North America) or 230 volts (most other regions)

Define the term 'load' in electrical terms.

• Load is the voltage supplied to a device.

• Load refers to the total electrical capacity of a circuit.

• Load is a device or component that consumes electrical power.

• Load is a measure of electrical resistance in a circuit.

What is the function of a circuit breaker?

• To increase the voltage in a circuit.

• To protect electrical circuits from overloads and short circuits.

• To provide a constant power supply.

• To measure electrical current flow.

List two types of electrical wiring commonly used in homes.

• Coaxial Cable

• Fiber Optic Cable

• Twisted Pair Cable

• Non-Metallic Sheathed Cable (NM) and Armored Cable (AC)

What is the significance of a grounding system?

• It helps in increasing electrical consumption.

• The significance of a grounding system lies in ensuring safety, protecting equipment, and stabilizing electrical systems.

• It is used to enhance the aesthetic appeal of electrical installations.

• It serves as a decorative element in electrical systems.

Explain the difference between AC and DC current.

• DC can reverse direction periodically.

• AC is always stronger than DC.

• AC reverses direction periodically; DC flows in one direction only.

• AC is used in batteries while DC is used in power lines.
