Worked practice questions

A battery pushes charge around a circuit. That special potential difference is called:

  1. Emf
  2. Elm
  3. Ebb
  4. Eon
Show answer and solution

Correct answer: A. Emf

1. A source must lift charge to a higher potential. 2. That lifting ability has its own name. 3. It is called emf. _Source: OpenStax University Physics Volume 2, Chapter 10, Direct-Current Circuits._

A student thinks emf is a kind of push in newtons. In truth emf is not a:

  1. Fibre
  2. Force
  3. Fluid
  4. Flame
Show answer and solution

Correct answer: B. Force

1. The name survives from older usage. 2. The quantity is measured in volts. 3. So emf is not a force at all. _Source: OpenStax University Physics Volume 2, Chapter 10, Direct-Current Circuits._

Inside a cell, negative charge is moved back to the negative terminal. The source acts as a:

  1. Charge pump
  2. Charge brake
  3. Charge mirror
  4. Charge magnet
Show answer and solution

Correct answer: A. Charge pump

1. The potential difference must be kept up. 2. Charge has to be driven back against the field. 3. So the source acts as a charge pump. _Source: OpenStax University Physics Volume 2, Chapter 10, Direct-Current Circuits._
