  1. Name: Date: Resistors & Capacitors 6. Draw the circuit diagram symbols for a variable resistor and a fixed resistor. 1. What does each strip on a resistor tell you? Label each ring on the diagram below: Fixed Resistor Variable Resistor • What does a capacitor do? • ____________________________________________________________________________________________________________ Explain in your own words what a resistor does ___________________________________________________________________________________________________________________________ How are non-polarised and electrolytic capacitors different? ________________________________________________________________________________________________________________________________________________ Why do some circuits need resistors? __________________________________________________________________________________ Make a list of what else you know about capacitors, you will need to add to this during the lesson if you learn anything new: ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Suggest two uses for a variable resistor . i)________________________________ Ii)________________________________ • How is a fixed resistor different to a variable resistor? • ____________________________________________________________________________________________________

  2. Non – polarized capacitor Electrolytic Capacitor Non conductive material Metal plate legs

  3. The battery gives some current to the capacitor which the capacitor then gives to the light bulb, once its full up.
