Electricity and Magnetism: SSC CGL Physics
Electricity and Magnetism has 15 questions in the SSC CGL Tier I bank, five from each of the 2023, 2024 and 2025 shifts. Four are short sums on current, resistance or energy; the rest are facts about magnets and devices such as the bell and the transformer. One page gives the two formulas and the facts.
The handout has every subtopic, worked example, formula and trap with answers shown. The formula sheet is the chapter’s formulas and traps alone, on one page.
