RL Series Phasor Construction

JEE Main asked RL Series Phasor Construction 2 times in 2 of the 108 shifts Lumi analysed, in 2024 and 2025. It belongs to Phasor Diagrams, in Alternating Current (Physics). The longest wait between two years asking it was 1 year.

Questions on this idea a shift, by year

2017–2026. Asked in 2024 and 2025. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Physics questions.
