Electric Circuits and Signals

Front

What is an electronic signal?

Back

Information that is sent as a pattern in a controlled flow of current through a circuit.

Front

What does bandwidth refer to?

Back

The amount of information that can be transmitted in bits per second.

Front

What is a wave pulse?

Back

A pulse of energy that travels through an electric circuit when it is closed.

Front

Define an electric circuit.

Back

A complete unbroken path through which electric charges can flow.

Front

What is Ohm's Law?

Back

The law that states that the resistance in a circuit is equal to voltage divided by current.

Front

What is the difference between an electronic signal and a digital signal?

Back

An electronic signal is a continuous signal that varies in amplitude, while a digital signal is a discrete signal that represents data in binary form.

Front

What is the role of a resistor in an electric circuit?

Back

A resistor limits the flow of electric current in a circuit.

Front

What is a semiconductor?

Back

A material that has electrical conductivity between that of a conductor and an insulator, used in electronic devices.

Front

What is the function of an insulator in an electric circuit?

Back

An insulator prevents the flow of electric current, protecting users and components.

Front

What is current in an electric circuit?

Back

The flow of electric charge, measured in amperes (A).
