Which of the following physical quantities has the dimensional formula [M^1 L^2 T^-3 A^-2]?

Question

Team JKExamLibrary · Accepted Answer

Electrical resistance (R) is Voltage/Current. Voltage (V) is Work/Charge. Work is [ML^2T^-2] and Charge is [AT]. So, V = [ML^2T^-3A^-1]. Therefore, R = V/A = [ML^2T^-3A^-2]. Memorizing the dimensional formula for resistance is highly recommended for competitive exams.
