  1. 9I Energy and Electricity

  2. 1. Which of these is not a form of energy? • Kinetic • Petrol • Light • Sound Response Grid

  3. 2. Which of these has the most GPE? • A parachutist on a runway • A parachutist going into a ‘plane • A parachutist jumping out of a ‘plane • A parachutist after landing Response Grid

  4. 3. What are the energy changes in a candle? • Heat to light • Heat to sound • Light to heat • Chemical to heat and light Response Grid

  5. 4. A machine is something which: • Changes energy • Creates energy • Destroys energy • Makes things Response Grid

  6. 5. The units for voltage are: • Amps • Ohms • Volts • Metres Response Grid

  7. 6. Which circuit diagram shows how to measure voltage? • A • B • C • D Response Grid

  8. 7. Voltage is: • Another name for current • A way of counting the cells in a circuit • A way of saying how much energy the current is carrying • Something which makes it difficult for current to flow Response Grid

  9. 8. Which statement is not true for a series circuit? • The voltage is always the same for all components • The voltage across each component depends on how much energy it uses • The voltage across all the components adds up to the voltage across the cell • The voltage can be measured using a voltmeter Response Grid

  11. 9. Where is electricity generated? • In the home • In a power station • In the mains • In the wires Response Grid

  12. 10. The energy in electricity comes from: • Energy stored in fuels, winds or water • Energy stored in food • Energy in the wires • Energy in the switches Response Grid

  13. 11. A cell is: • A jail • A store of chemical energy • Mains electricity • A power pack Response Grid

  14. 12. High voltages are dangerous because: • They cost a lot to produce • They do not transfer much energy • They can transfer a lot of energy • They are poisonous Response Grid

  15. 13. Which statement is true? • You always put more energy into a machine than you get out • You always get more energy out of a machine than you put in • The amount of energy you get out of a machine is always exactly the same as the energy you put in • The amount of energy you get out of a machine does not depend on the amount you put in Response Grid

  16. 14. Which is the correct energy flow diagram for a television? • A • B • C • D Response Grid

  17. 15. Which forms of energy are often produced as wasted energy? • Heat and light • Heat and sound • Sound and light • Sound and kinetic Response Grid

  18. 16. An efficient machine: • Does not waste much energy • Wastes a lot of energy • Is more expensive to run than an inefficient machine • Is more expensive to buy than an inefficient machine Response Grid
