Question

dimensional formula of Capacitance reactance Xc

Answer 1

Unit of capacitance 
= Coulomb/Volt
=$\frac{ Coulomb^{2} }{Joule}$
=$\frac{(Amp-sec)^{2} }{kg- m^{2}/ sec^{2} }$
=>Dimensional formula of capacitance is 
$M^{-1}* L^{-2}* T^{4}* A^{2}$

Answer 2

Unit of capacitance 
= Coulomb/Volt
