7.4 Schematic Diagrams

What is the primary function of symbols in schematic diagrams?

• To represent each element in the circuit.

• To decorate the diagram.

• To show the size of components.

• To indicate the color of wires.

Why might a schematic diagram be preferred over a physical drawing for complex circuits?

• It is easier to understand the connections between elements.

• It is more expensive to produce.

• It takes longer to draw.

• It uses more paper.

If you wanted to show how a circuit is connected without showing its real-life appearance, what would you use?

• A schematic diagram

• A photograph

• A written description

• A 3D model

Which of the following is an application of schematic diagrams outside of engineering?

• Helping electricians assemble real-life electrical components.

• Cooking recipes.

• Writing stories.

• Painting landscapes.

What does a schematic diagram use to represent electrical components?

• Symbols

• Numbers

• Colors

• Shapes

All circuits contain at least which of the following components?

Choose all that apply

• Voltmeter

• Voltage source

• Conducting wires

• resistors

• motors

What does a switch do in a circuit?

• Controls the flow of current by turning it on or off

• Provides energy to the circuit

• Limits the current

• Stores electrical energy

If a circuit does not have a voltage source, what will happen?

• No current will flow

• The resistance will increase

• The switch will not work

• The wire will break

Which of the following is NOT a function of a switch in a circuit?

• To provide energy

• To control current flow

• To turn devices on or off

• To manage resistors

What does any device that uses electrical power have?

• Resistance

• Capacitance

• Inductance

• Voltage
