Strand 3: Electric & Magnetic fields
and their interactions

Investigations & Demonstrations

3.1 Charge Interactions

• To show that all static charge resides on the outside of a hollow metal conductor.
• To show that static charge on a conductor tends to accumulate where the conductor is most pointed.
  
  

3.2 Modelling Electric Fields

>    Electric fields in the lab

3.3 Electric Circuits

• To verify the relationship between current flowing
  through and the voltage across an ohmic conductor.
• To investigate the effect of varying temperature on the resistance of a conductor.
• To investigate the relationship between current flowing through and the voltage across a non-ohmic conductor (filament bulb).
• To model resistors in series and in parallel in an electrical circuit.
• To investigate the relationship between current flowing through and the voltage across a non-ohmic conductor (diode).
