Question

what is dimensional formula of capacitance?

Answer 1

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

Answer 2

The dimensional formula of capacitance is M^-1 L^-2 T^4 I^2
