Electricity is defined as ______________.

  1. the flow of electrons along a conductor
  2. the flow of ions along a conductor
  3. the movement of charges
  4. static electricity

Answer(s): A



A conductor is any material that ______________.

  1. has no free electrons
  2. has many free electrons
  3. has free ions
  4. has free protons

Answer(s): B

Explanation:

Conductors have free electrons that are easily moved along with the right kind of push or force. There are a number of ways to cause these electrons to progress along a conductor. Heat, light, magnetism, chemicals, pressure, and friction can cause the generation of an EMF useful in causing electrons to move along a conductor.



Convention current flow is from __________________.

  1. + to +
  2. − to +
  3. + to −
  4. − to −

Answer(s): C

Explanation:

Conventional current flow is said to be from + to −. This idea was originally used by Ben Franklin to explain the conduct of lightning. This conventional flow is still used today by electrical engineers and people working in physics.



Electron flow is from _______________.

  1. + to +
  2. − to +
  3. + to −
  4. − to −

Answer(s): B

Explanation:

Electron flow can be demonstrated to flow from − to +. The action that takes place in a vacuum tube indicates that the + attracts the − electron to cause it to move from − to +.
