Back

The best way to lift an object is by bending your knees and keeping your back straight.

Front

True or False? Light is generated by electrons flowing through a resistor.

Back

False. Light is generated by the movement of electrons in certain materials, not specifically through a resistor.

Front

What is the fundamental concept of electricity and electronics?

Back

All of electricity and electronics is based on the movement of electrons through a material and applying them to a load.

Front

As a conductor length increases, what happens to its resistance?

Back

As a conductor length increases, its resistance also increases.

Front

Define 'conductor' in the context of electricity.

Back

A conductor is a material that allows the flow of electric current, typically metals like copper and aluminum.

Front

What is 'ampacity'?

Back

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

Front

Explain the term 'insulation' in electrical systems.

Back

Insulation is a material that resists the flow of electric current, used to protect conductors and prevent short circuits.

Front

What is the role of a load in an electrical circuit?

Back

A load is any device that consumes electrical energy, such as a light bulb or motor.

Front

True or False? Resistance decreases as the temperature of a conductor increases.

Back

False. Resistance typically increases as the temperature of a conductor increases.
