Exam 2: Principles of Telecommunications Technology

Because the charges inherent in electrons and protons are bound to balance each other through static electricity, these charges are also called ____________________.

The charge flowing through a wire each second is measured in volts. _________________________

Static electricity is the release of an accumulated charge in some material or object.

When used in an electric circuit, a coil of wire is called a(n):

Does the term electromagnetic refer to a wave that contains a combination of electric and magnetic forces?

The material over which electric current readily flows is known as:

Materials that do not allow electric current to flow easily are called:

A(n) ____________________ is the characteristic of a material that enables it to exert force on another material.

Is voltage measured in amperes?

Are electrons found at the center of an atom?

The pressure that the electric current exerts on its conductor is known as amperes.

The use of a conductor to divert unused or potentially harmful charges to an insulator, where they will be stopped or absorbed is referred to as:

Can you use the words current electricity and electric current interchangeably?

The magnetic effect produced by an electric current is known as:

What is commonly equated to the strength of an electric current?

Match each statement below with the correct item -When current is manipulated to transmit information.

The pressure that an electric current exerts is known as amperes. _________________________

Which of the following is a release of an accumulated charge in some material or object?

The term frequency refers to the number of cycles in a sine wave that are completed within a specified time frame. _________________________

Grounding is the use of a conductor to divert unused or potentially harmful charges to an insulator, where they will be stopped or absorbed. _________________________
