1- What is Frequency?
Frequency is the Reciprocal of Time Period. 

F = 1/T , Unit - Hz

It also defines the Number of Oscillation per unit time.

F = No. of Oscillation / Unit Time

2- What is Angular Frequency in Electrical Engineering?
Angular Frequency is Define as the Angular Displacement covered in one Second.

ω = 2π/T = 2πF

3- Type of A.C. Function
Any A.C. (Alternator Current) Function has Four Values

1- Instantaneous - Any A.C. Function which depends on time is known as instantaneous A.C. Function.
V = Vm Sin ωt or I = Im Sin ωt

2- Average - It is that value of A.C. Function which is equivalent to D.C. Value.

3- Peak - Peak Value is the Maximum value of any A.C. Function.

4- RMS - RMS is Root Mean Square Value of any A.C. Circuit.

4- What is Capacitor?
A Capacitor is formed when two plates (conductor) are separated by a gap distance through a dielectric.

A Capacitor opposes any change in the voltage it stores energy in the electrostatic field.

Definition - A Capacitor is Define as the charge per unit voltage.

C = Q/V, Unit = Farad
