Series Phasor Addition

JEE Main asked Series Phasor Addition 3 times in 3 of the 108 shifts Lumi analysed, in 2021 and 2022. It belongs to Phasor Diagrams, in Alternating Current (Physics). The longest wait between two years asking it was 1 year. In 2022 it came in more than one shift of the same year.

Questions on this idea a shift, by year

2017–2026. Asked in 2021 and 2022. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Physics questions.
