Normal practice, or a Simulated test

Both use the same questions. Normal practice is untimed and needs no account: choose an option and the answer and solution appear at once. The Simulated test is the real computer-based format, with one 25-minute clock, a question palette and full screen, and your score, the key and the solutions arrive when you submit.

Untimed

Every question on one page, loading as you scroll. Choose an option and see straight away whether it was right.

  • No timer. Nothing to start and nothing to submit. Stop whenever you like.
  • Answered as you choose. Tap an option and it is marked at once, with the correct answer shown.
  • Solutions in place. The explanation, and the video where one has been added, sit under the question.
  • Open to guests. Normal practice needs no sign-in.

Timed CBT

The computer-based test format: one clock, a question palette, and a score the moment you submit.

  • A clock that does not pause. 25 minutes from the moment you begin, and the paper is submitted for you when it reaches zero.
  • Question palette. Answered, not answered and marked for review, section by section, as the real interface has it.
  • Full screen, proctored. The test takes over the screen; leaving it three times submits the paper.
  • Answers hidden until you submit. The key, the explanations and your score all arrive together at the end.

About this test

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.

FAQs about Electricity and Magnetism – GK Quiz with Answers – Level 1

What is Ohm's law in electricity?
Ohm's law states that, at constant temperature, the current through a conductor is directly proportional to the potential difference across it. It is written as V equals I times R.
What is the SI unit of electric charge?
The SI unit of electric charge is the coulomb.
What is the difference between an electric motor and a generator?
An electric motor converts electrical energy into mechanical energy. A generator converts mechanical energy into electrical energy.
Why are household appliances connected in parallel?
In parallel, each appliance gets the full supply voltage and can be switched on or off on its own. If one appliance fails, the others keep working.
