Why is insulation resistance testing important for the maintenance of electrical motors?

Why is electrical power transmitted at high voltage and low current?
Answer : Power loss in transmission lines is given by: $$ P_{\text{loss}} = I^2 R $$ where $I$ is the current and $R$ is the line resistance. * If power is transmitted at **low voltage**, ... kV) using **step-up transformers** for transmission, and then step it down near consumers for safe distribution. ...

What is the difference between AC (Alternating Current) and DC (Direct Current)?
Answer : Direct Current (DC): The flow of electric charge is in one constant direction. Sources include batteries, solar cells, and DC power supplies. It is mainly used in electronics, charging, ... because it can be easily transformed to higher or lower voltages using transformers, reducing energy loss....
