RMS Voltage and Current | Why RMS value is used? 

RMS Voltage and RMS Current is the root mean square value which is used to define the magnitude of AC quantities like voltage and current etc. In this video my topics of discussion is
1- difference between AC and DC
2- How we compute average value
3- How we compute RMS value
4- Why RMS is used instead of average value
5- What is significance of RMS value
6- Which value is used in meters and power calculations
