2. What is the equation for force?

  • Force = change in momentum / time taken
  • force = change in momentum x current
  • force = change in momentum / current
  • force = change in resistance / potential difference

3. What is the equation for energy transferred?

  • energy transferred = charge flow x potential difference
  • energy transferred = current x resistance
  • energy transferred = resistance x power
  • energy transferred = current x power

4. What is the equation for magnetic flux density (B)?

  • B = length x width x force
  • B = force / current x length
  • B = length x width x height
  • B = force x current x length

5. What is the eqaution for density?

  • density = mass / area
  • density = mass / volume
  • density = area x mass
  • density = mass x volume
