Electricity and Magnetism GK Practice Quiz Level 1: Basics and SI Units
Students starting General Awareness physics can use this Level 1 Aptitude360 quiz as a first round on electricity and magnetism. It asks direct factual questions on SI units, Ohm's law, measuring instruments, magnetic field lines and safe household wiring. Every question comes with a written explanation.
What this basic electricity and magnetism quiz tests
- SI units of charge, potential difference, resistance, resistivity and power
- Ohm's law, Joule's law of heating and the formula for electric power
- Ammeters and voltmeters and how each is connected in a circuit
- Series and parallel resistors and how resistance changes with the length of a wire
- Materials such as tungsten filaments, heating-element alloys and metals for transmission lines
- Magnetic field lines, solenoids, compass poles and MRI
- Motors, generators, fuses, overloading, short circuits and the commercial unit of electrical energy
Key concepts for electricity GK beginners
- Which device converts electrical energy into mechanical energy and which does the reverse
- Why home appliances are wired in parallel
- Why field lines never cross and what crowded field lines show
- Scientists linked to key laws and discoveries, such as Ohm and Faraday
- The device that works on Fleming's left-hand rule
Revision tips for electricity and magnetism basics
- Keep a one-page list pairing each physical quantity with its SI unit and measuring instrument
- Remember that an ammeter goes in series and a voltmeter goes in parallel
- Revise household safety terms together: fuse, overloading and short circuit
Who should take this Level 1 quiz
It suits beginners in General Awareness physics who want to fix the core facts before moving on to the next level.
