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 35-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. 35 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.

Electricity and Magnetism GK Practice Quiz Level 3: Circuits and Magnetic Rules

This Electricity and Magnetism GK Quiz, Level 3, is a general science practice set on electric circuits, the magnetic effect of current and household electricity. It tests how well you apply circuit laws, magnetic rules and the working of common devices. On Aptitude360, the questions mix statement checks, list matching and short numerical problems on resistance, heating and power.

Topics covered in this electricity and magnetism set

  • Electric charge, current, potential difference and their SI units
  • Ohm's law, resistivity, and how length and temperature affect resistance
  • Equivalent resistance of series, parallel and mixed resistor combinations
  • Joule's law of heating, expressions for electric power and the commercial unit of electrical energy
  • Magnetic field lines, solenoids, electromagnets and Oersted's discovery
  • Fleming's left-hand rule, right-hand thumb rule, motors, generators and electromagnetic induction
  • Domestic circuits: fuses, short circuits, parallel wiring, and materials such as tungsten and nichrome

Key electricity concepts to revise

  • What the thumb, forefinger and middle finger stand for in Fleming's left-hand rule
  • Why an ammeter is connected in series and a voltmeter in parallel
  • Why magnetic field lines never intersect and how they run outside a magnet
  • How direct current from a cell differs from alternating mains supply
  • Which devices work on induction and which on the force on a current-carrying conductor

Revision tips for electricity and magnetism GK

  • Reduce parallel groups of resistors first, then add the series resistors
  • Keep one table of quantities, SI units and symbols for matching questions
  • Link each scientist to one discovery, such as Oersted with the magnetic effect of current and Faraday with induction

Who should take this physics GK quiz

Aspirants revising general science for competitive exams, whether in Chandigarh or elsewhere, who already know the basic ideas of electricity and want application-based practice.

FAQs about Electricity and Magnetism – GK Quiz with Answers – Level 3

What is Fleming's left-hand rule used for?
It gives the direction of the force on a current-carrying conductor placed in a magnetic field. The forefinger shows the field, the middle finger shows the current and the thumb shows the force, which is the principle behind an electric motor.
What is the difference between an electric motor and a generator?
A motor converts electrical energy into mechanical energy using the force on a current-carrying conductor in a magnetic field. A generator converts mechanical energy into electrical energy through electromagnetic induction.
Why are household appliances connected in parallel?
In parallel wiring each appliance gets the full supply voltage and can be switched on or off independently. If one appliance fails, the others keep working.
Why is a fuse used in an electric circuit?
A fuse wire melts when the current becomes too large, for example during a short circuit or overloading. This breaks the circuit and protects appliances and wiring from damage.
