1) Electricity Surge - add 5 points to your score! 2) Draw a parallel circuit with 2 bulbs and an ammeter measuring voltage at one buln. 3) Why are resistors added to circuits? 4) Explain what happens to the current in a parallel circuit. 5) What unit is resistance measured in? 6) What symbol do we use to show resistance? 7) Explain which kind of circuit you would use for Christmas lights and why? 8) List 3 things you have done today you could not have done without electricity. 9) Draw a series circuit with an open switch and 1 bulb, a buzzer and a motor. 10) Explain why the current in a parallel circuit is the same just before and just after the cell. 11) The supply voltage is 6V. Bulbs 1 and 2 are identical. What voltage is measured across bulb 1? 12) Draw a diagram to show how you would measure current in a parallel circuit at 2 different points. 13) Draw a diagram to show how you would measure voltage in a series circuit at 2 different points. 14) Draw and label 5 symbols we use when drawing circuits. 15) A series circuit has a 2 bulbs with a voltage of 5V and 1 bulb with a voltage of 11V. What is the average voltage of the 3 bulbs? 16) State a form of electricity we see in nature.
