DigE Ch05 Basic Electrical Circuit Materials

Front

What should be considered when replacing an appliance switch?

Back

Ampacity and voltage rating.

Front

What is the relationship between the diameter of conductors and the current they can carry?

Back

Conductors with a large diameter can carry more current than small-diameter conductors of the same material.

Front

True or False: A fuse's small wire burns and breaks when overloaded.

Back

True.

Front

What happens to the resistance of a conductor as its length increases?

Back

As a conductor length increases, its resistance increases.

Front

What does excessive current cause in a circuit?

Back

Overheating.

Front

Define ampacity.

Back

Ampacity is the maximum amount of electric current a conductor or device can carry before sustaining immediate or progressive deterioration.

Front

What is the purpose of a fuse in an electrical circuit?

Back

A fuse protects the circuit by breaking the connection when the current exceeds a certain level.

Front

Explain the term 'voltage rating' in electrical components.

Back

Voltage rating is the maximum voltage that an electrical component can handle safely without risk of failure.

Front

What is the effect of increasing the temperature on the resistance of a conductor?

Back

Increasing the temperature generally increases the resistance of a conductor.

Front

What is the difference between a toggle switch and a slide switch?

Back

A toggle switch is operated by a lever that moves up and down, while a slide switch is operated by sliding a knob or lever from one position to another.
