Worked practice questions

An electrician measures how fast charge flows past a point. That quantity is electric:

  1. Current
  2. Contact
  3. Contour
  4. Coupling
Show answer and solution

Correct answer: A. Current

1. Charge is moving through a conductor. 2. The rate of that flow is the quantity wanted. 3. That quantity is electric current. _Source: OpenStax College Physics 2e, Chapter 20, Electric Current, Resistance, and Ohm's Law._

One coulomb of charge passing a point in one second defines one:

  1. Aperture
  2. Ampere
  3. Angstrom
  4. Antenna
Show answer and solution

Correct answer: B. Ampere

1. The SI unit of current pairs charge with time. 2. One coulomb per second is the standard amount. 3. That unit is the ampere. _Source: OpenStax College Physics 2e, Chapter 20, Electric Current, Resistance, and Ohm's Law._

Fuses, circuit breakers and many appliances are rated in units of:

  1. Amperes
  2. Aggregates
  3. Altitudes
  4. Amplitudes
Show answer and solution

Correct answer: A. Amperes

1. The rating limits how much charge may flow per second. 2. That is a statement about current. 3. So they are rated in amperes. _Source: OpenStax College Physics 2e, Chapter 20, Electric Current, Resistance, and Ohm's Law._
