Electricity Flashcards

Light, heat, chemical and magnetic changes are all produced by:

Most of the electricity you use daily consists of a flow of tiny, negatively charged particles called:

The movement of electricity along a path called a conductor is a(n):

Materials that best transport electricity are called:

Which of the following materials does NOT allow a current to pass through it?

An ampere is a unit of electric:

A volt is a unit of electric:

A measure of how much electrical energy is being used is known as a:

A current in which electrons move at an even rate and flow in only one direction is called:

When a blow dryer is on and air begins to flow, you have an example of a(n):

When too many appliances are put on one circuit and operated all at the same time, this is known as:

Fires in electrical circuits can occur if:

Dropping an electrical appliance into water, making it a foreign conductor, causes a(n):

Which of the following devices breaks the flow of current when an overload occurs?

Which of the following should NOT be done if a fire results from an overload of an electric circuit?

Electricity Basics

Light, heat, chemical and magnetic changes are produced by electricity.
Electricity consists of a flow of negatively charged particles known as electrons.

Current and Conductors

Electric current refers to the movement of electricity along a conductor.
Conductors are materials that effectively transport electricity.
Insulators do not allow current to pass through, such as alcohol.

Units of Measurement

An ampere measures electric strength.
A volt measures electric pressure.
A watt measures electrical energy consumption.

Types of Current

Direct current (DC) has electrons moving at a constant rate in one direction.
A closed circuit permits the flow of electricity, whereas an open circuit does not.

Circuit Safety

Overloading occurs when too many appliances are on a single circuit, leading to excess current flow.
Electrical fires can happen due to an overloaded circuit and multiple appliances sharing the same socket.
Dropping an appliance in water causes a short circuit by creating a foreign conductor.

Circuit Breakers

A circuit breaker interrupts the flow of current during overload situations, enhancing safety.
It's crucial to avoid using water to extinguish electrical fires; instead, use a fire extinguisher or smother it.

Additional Safety Considerations

Opening a circuit intentionally can prevent appliance damage, but it shouldn't be done during a fire caused by overload.
