Question

A quantity` X` is given by `epsilon_(p) L(delta V)/(delta t)` , where `epsilon_(p)` is the permitivity of free space ,L is a length , `delta V` is a potential difference and ` deltat ` is a time interval . The dimensional formula for `X` is the same as that of
A. Resistance
B. Charge
C. Voltage
D. Current

Answer 1

Correct Answer - D
Dimensionally `epsilon_(0)L = C`, where C = capacitance
Dimensionally `C Delta V = q` , where `q` is charge
Dimensionally `(q)/(Delta t) = I` , where `I` is current
