3 ICT To solve the practical paper 2 of IGCSE 15 with screen shots. PHYSICS HOLIDAY-HOMEWORK FOR GRADE-X ON ELECTRICITY 1.The diagram shows apparatus that can be used to make a magnet. Which metal and which power supply are used to make a permanent magnet? 2. A positively charged plastic rod is placed just above a thick metal plate. The metal plate rests on an insulator and is connected to the earth by a wire.
4 A student disconnects the earthing wire and then removes the positively charged rod. The experiment is repeated. This time the student removes the positively charged rod and then removes the earthing wire. Which statement is correct? A When the earthing wire is disconnected first, the metal plate becomes positively charged. B When the earthing wire is disconnected first, the metal plate becomes negatively charged. C When the plastic rod is removed first, the metal plate becomes positively charged. D When the plastic rod is removed first, the metal plate becomes negatively charged. 3. The resistance of a wire depends on its length l and on its cross-sectional area A. The resistance is A directly proportional to l and directly proportional to A. B directly proportional to l and inversely proportional to A. C inversely proportional to l and directly proportional to A. D inversely proportional to l and inversely proportional to A. 4. In the circuit shown, the ammeter reads 2.0 A and the voltmeter reads 12 V. How much energy is transferred by the resistor in 10 seconds? A 2.4 J B 14.4 J C 240 J D 1440 J 5. The diagram shows part of an electrical circuit. \ The current in the 4.0 Ω resistor is 3.0 A. What is the current in the ammeter? A 4.5 A B 6.0 A C 9.0 A
5 D 12.0 A 6. The circuit diagram shows a thermistor in a potential divider. A voltmeter is connected across the thermistor. The graph shows how the resistance of the thermistor changes with temperature As the thermistor becomes warmer, what happens to its resistance and what happens to the reading on the voltmeter? 7. A circuit-breaker is designed to protect a circuit which usually carries a current of 2 A. The time taken to break the circuit depends on the current, as shown in the graph.
6 What happens when the current in the circuit is 2 A and what happens when the current is 18 A? 8. An engineer uses the potential divider shown in the diagram. He needs the output voltage to be one tenth ( 101 ) of the input voltage. Which pair of values could he use for the two resistors X and Y?
7 9.The diagram shows a 10 Ω resistor and a 20 Ω resistor connected in a potential divider circuit. What is the reading on the voltmeter? A 4.0 V B 6.0 V C 8.0 V D 12.0 V 10.In the circuit shown, only one of the fuses has blown, but none of the lamps is lit. Which fuse has blown?
8 11 Either a fuse or a circuit-breaker can be used to protect electrical cables from large currents that could cause overheating. When a fuse is used, where should it be connected, and when a circuit-breaker is used, where should it be connected? 12. When a door bell is rung, what is being used as the : a) input sensor b) output device 13. What is the purpose of a) a rectifier b) a condenser 14. a).draw the symbol for a NOR GATE b) Draw a truth table to represent the operation of this gate. c) Write a sentence summarising its operation. 15. Using the correct symbols show the following: a) The outputs of two AND gates are connected to the inputs of a third AND gate b ) When is the output of this third gate ON? c) Suggest a use for this combination of gates.
