Frequently asked questions

What makes a Current Electricity question "important" for JEE?

Important questions test core concepts that appear frequently across JEE Main and Advanced papers — definitions, standard formulas, and classic problem types.

Which subtopics in Current Electricity are high-weightage?

Key areas include Electric current: drift velocity, mobility and their relation with electric current, Ohm's law, electrical resistance, I-V characteristics of Ohmic and non-ohmic conductors, Electrical energy and power, electrical resistivity and conductivity, Series and parallel combinations of resistors, temperature dependence of resistance, and more. Prioritise these before moving to edge cases.

How many important questions should I revise?

Revise 30–50 important MCQs per unit in the last month before JEE. Focus on questions you got wrong at least once.
