Tolerance rating is expressed as plus (+) or minus (-) value in ± Pico farads for low-value capacitors which are less than 100pf or as a percentage (± %) higher than 100pf for high-value capacitors. It can range from -20% to +80% i.e. If a 100µF capacitor with a tolerance of ±20% can vary from 80µF to 120µF.
The specific capacity of $pu{75 mAh/g}$, expressed in SI unit, is : $$pu{75 mAh/g = 75*0.001 A*3600 s/g = 270 C/g}$$ If the battery has a nominal voltage of $pu{1.7 V}$, it means that it is able to produce a total energy which is not expressed in watts (as mentioned in the original text), but in joules.

However, the potential drop (V_1 = Q/C_1) on one capacitor may be different from the potential drop (V_2 = Q/C_2) on another capacitor, because, generally, the capacitors may have different capacitances. The series combination of two or three capacitors resembles a single capacitor with a smaller capacitance. Generally, any number of capacitors connected in …
When the charge is expressed in coulombs, potential is expressed in volts, and the capacitance is expressed in farads, this relation gives the energy in joules. Knowing that the energy stored in a capacitor is (U_C = Q^2/(2C)), we can now find the energy density (u_E) stored in a vacuum between the plates of a charged parallel-plate capacitor.
In the SI system, capacitance is measured in Farads (F). One Farad represents the capacitance of a system when one coulomb of electrical charge is stored per volt of potential difference (voltage) across a capacitor. In …
The capacity of a capacitor used in power factor correction is expressed as kVAr.. Important Points. Power Factor: The overall power factor is defined as the cosine of the angle between the voltage and current.; In AC circuits, the power factor is also defined as the ratio of the real power flowing to the load to the apparent power in the circuit.

The Farad is a very large unit, and to find a capacitor''s value expressed in farads was at one time unheard of. Today, 2.5 V, 25 F super-capacitors, although rare, can be bought from electronics suppliers. The value of most electrolytic capacitors is normally expressed in microfarads, even when the figure is 10,000 microfarads.
