Topic 2 - Electricity

• All the circuit symbols:

  
• The person could receive a fatal electric shock if the kite was very close to, but not touching the power cable.

  Explain why (3)

  • electric field strength is very high
  • causing the air to become ionised
  • kite conducts change to the person
• When the volume of gas in the syringe increased, the pressure on the inside walls of the syringe decreased.

  Explain why (3)

  • less frequent collisions between the particles and the walls of the syringe
  • causing a lower average force on the walls of the syringe
  • and pressure is the total force per unit area
