Transcript

  • 1. 02/06/14 P12 Electricity Syllabus statements
  • 2. 12.1 1. Demonstrate understanding of current, potential difference, e.m.f. and resistance, and use with their appropriate units. 2. State that charge is measured in coulombs (C). 3. Use and describe the use of an ammeter and a voltmeter.
  • 3. 12.2 Electric charge 1. Describe and interpret simple experiments to show the production and detection of electrostatic charges. 2. State that there are positive and negative charges. 3. Describe an electric field as a region in which an electric charge experiences a force.
  • 4. 12.2 Electric charge 4. State that unlike charges attract and that like charges repel. 5. Distinguish between electrical conductors and insulators and give typical examples.
  • 5. 12.3 Current, electromotive force & potential difference 1. State that current is related to the flow of charge. 2. Demonstrate understanding that a current is a rate of flow of charge and recall and use the equation I = Q / t. 3. Use the term potential difference (p.d.) to describe what drives the current between two points in a circuit.
  • 6. 12.3 Current, electromotive force & potential difference 4. Distinguish between the direction of flow of electrons and conventional current. 5. Demonstrate understanding that e.m.f. is defined in terms of energy supplied by a source in driving charge round a complete circuit.
  • 7. 12.4 Resistance 1. State that resistance = p.d. / current and understand qualitatively how changes in p.d. or resistance affect current. 2. Recall and use the equation R=V/I 3. Describe an experiment to determine resistance using a voltmeter and an ammeter.
  • 8. 12.4 Resistance 4. Recall and use quantitatively the proportionality between resistance and length, and the inverse proportionality between resistance and crosssectional area of a wire. 5. Relate (without calculation) the resistance of a wire to its length and to its diameter.
  • 9. 12.5 Electrical energy 1. Recall and use the equations: P=IV and E=IVt
  • 10. 12.6 Dangers of electricity 1. Identify electrical hazards including: • damaged insulation • overheating of cables • damp conditions. 2. Demonstrate understanding of the use of circuit-breakers. 3. Demonstrate understanding of the use of fuses.
