About this test

This Science (विज्ञान) mock test is made for Class 10 students who want to revise important chapters and check how well they understand them. It includes questions from Light (प्रकाश), Human Eye (मानव नेत्र), Electricity (विद्युत), Magnetic Effects of Electric Current (विद्युत धारा के चुंबकीय प्रभाव) and Our Environment (हमारा पर्यावरण), so you can practise both concepts and numerical problems. Solve it in one sitting with a timer, without looking at your book. Afterwards, check each answer carefully and note the topics where you lost marks. Regular practice like this builds speed and confidence for school tests and the board exam (बोर्ड परीक्षा).

What is the SI unit of resistance (प्रतिरोध)?

Ohm (Ω).

State Ohm's law (ओम का नियम).

The current through a conductor is directly proportional to the potential difference across its ends, if the temperature stays the same (V = IR).

Which rule gives the direction of force on a current-carrying conductor in a magnetic field?

Fleming's left-hand rule (फ्लेमिंग का बायाँ हाथ नियम).

What is the 10 per cent law (10 प्रतिशत नियम) in a food chain?

Only about 10 per cent of the energy at one trophic level passes to the next level.
