⚡ Spark Your KnowledgeVersión en línea An electrifying science quiz designed to test your knowledge on electricity! From static charges to powerful currents, challenge yourself with exciting questions that will brighten up your mind and spark your curiosity. por NURUL HAFIFI 1 1.What are meant by electrostatic charges? Apakah maksud caj elektrostatik? a Flow of electrons in a conductor b Electric charges that are do not move c Power of a battery to light a bulb d Electric current flowing in a circuit 2 2.What are the two types of electric charges that exist in electrostatics? Nyatakan dua jenis cas elektrik yang wujud dalam elektrostatik. a Proton and neutron b Electron and photon c Positive charge and negative charge d Heat charge and light charge 3 3.Objects carrying similar charges will ________, while objects carrying opposite charges will ________. Objek yang mempunyai cas sejenis akan ________, manakala objek yang mempunyai cas berbeza akan ________. a Repel, attract b Attract, repel c Attract, stick d Repel, flow 4 4.Which of the following is an example of an electrostatic phenomenon in daily life? Antara berikut, yang manakah contoh fenomena elektrostatik dalam kehidupan harian? a A bulb lights up when the switch is closed b Hair is attracted to a plastic ruler after it is rubbed c A fan rotates when connected to a socket d A battery charges a phone 5 5.Why does hair get attracted to a plastic ruler after rubbing? Mengapa rambut tertarik ke arah penggaris plastik setelah digosok? a The hair becomes lighter b The ruler gains an opposite charge from the hair c The hair becomes oily and sticks d Heat from friction pulls the hair 6 6.What happens when a balloon is rubbed on a shirt and then placed against a wall? Apakah yang berlaku apabila belon digosok pada baju kemudian dilekatkan pada dinding? a The balloon loses air and sticks b The balloon gains charge and is attracted to the wall c The wall produces heat that holds the balloon d Friction pushes the balloon onto the wall 7 7.What is meant by electric current? Apakah maksud arus elektrik? a Electric charges accumulated on an object b Flow of electrons in a closed circuit c Amount of energy in a battery d Resistance occurring in a conductor 8 8.How can moving charges produce an electric current? Bagaimanakah cas yang bergerak dapat menghasilkan arus elektrik? a By producing heat in the conductor b By moving through a conductor in a closed circuit c By accumulating on the surface of objects d By releasing light while moving 9 9.Complete the sentence: Electric current is produced when ______ move in a ______. Lengkapkan ayat: Arus elektrik terhasil apabila ______ bergerak dalam ______. a Protons, air b Electrons, complete circuit c Neutrons, battery d Positive charges, bulb 10 10.What is the main difference between electric current and static electricity? Apakah perbezaan utama antara arus elektrik dengan cas statik? a Electric current flows, static electricity does not move b Electric current is not useful, static electricity is useful c Electric current exists in hair, static electricity in batteries d Electric current is measured in volts, static electricity in amperes 11 11.A student states “electric current is the flow of electrons.” Is this statement correct? Seorang pelajar menyatakan “arus elektrik adalah aliran elektron”. Adakah pernyataan ini benar? a Incorrect, because electric current is static electricity b Incorrect, because electric current is heat energy c Correct, because electric current is produced by the flow of electrons in a conductor d Correct, because electric current is produced by moving protons 12 12.What is the actual direction of electron flow in a circuit? Apakah arah aliran sebenar elektron dalam sesuatu litar? a From positive to negative b From negative to positive c From earth to battery d From neutral to positive 13 13.Why can electric current only flow in a complete circuit? Mengapakah arus elektrik hanya dapat mengalir dalam litar yang lengkap? a So that electrons have a closed path to move b So that the battery can produce heat energy c So that the resistance of the conductor decreases d So that the bulb can emit light longer 14 14.What is the main function of a Van de Graaff generator? Apakah fungsi utama penjana Van de Graaff? a To produce continuous electric current b A device that produces electric charges c To convert electrical energy into mechanical energy d To measure voltage in a circuit 15 15.Why does a person’s hair stand on end when touching the sphere of a Van de Graaff generator? Mengapakah rambut seseorang akan berdiri tegak apabila menyentuh sfera penjana Van de Graaff? a The hair loses moisture b The hair gains each strand gets the same charge and repels one another. c Hot air pushes the hair upward d Charges flow to the ground through the hair 16 16.What happens if someone touches the sphere of a Van de Graaff generator with a fingertip? Apakah yang berlaku jika seseorang menyentuh sfera penjana Van de Graaff dengan hujung jari? a Continuous current flows b A static discharge occurs in the form of a small spark or mild electric shock sensation. c The finger absorbs charges and becomes magnetic d Nothing happens 17 17.The basic principle demonstrated by a Van de Graaff generator is that… Prinsip asas penjana Van de Graaff menunjukkan bahawa… a Same charge attract each other. b Different charges repel each other c Same charges repel each other d Charges cannot move through a conductor 18 18.Which of the following is NOT an effect of using a Van de Graaff generator? Antara berikut, yang manakah BUKAN kesan penggunaan penjana Van de Graaff? a Hair standing on end b Small sparks when touched c Balloon sticking to the wall d Charges accumulating on the metal sphere
