Series and Parallel Combinations

JEE Main asked Series and Parallel Combinations 17 times in 17 of the 108 shifts Lumi analysed, in 2020, 2021, 2022, 2023, 2024 and 2026. It belongs to Parallel Plate Capacitors, in Electrostatic Potential and Capacitance (Physics). The longest wait between two years asking it was 2 years. In 2020, 2021, 2022, 2023 and 2024 it came in more than one shift of the same year.
