Equivalent circuit of a capacitor

The equivalent circuit of an actual capacitor shown below indicates that there are other characteristics besides capacitance to be considered.

i) Inductance (L) of the leads and plates
ii) Resistance (R1) of dielectric (leakage resistance)
iii) Resistance (R2) of leads and plates (effective series resistance)
iv) C is measured capacitance
