Easy Topics in JEE Main Physics

  • Electrostatics is a very lengthy but is a easy topic. Mostly three to four questions are asked from this topic every year.
  • Current Electricity is a small topic but is very scoring. Questions from the topic like colour code of resisters, Ohm’s Law, etc. are frequently asked in the JEE Main exam.
  • Electro-magnetic Induction and Alternating Current is also easy topic and is an important topic for JEE Main. One to two questions are asked from these two topics each year.
  • Semiconductor & Electronic Devices, Communication, Units & Dimensions, Measurement of error (Absolute and Relative), Instruments. These are very small and scoring topics. One question is usually asked from each of these topics in JEE Main. So, you should not skip these as they can easily score 16-20 marks.
