When to use I²R, V²/R or VI while calculating Electric Power?

I came across a question that was asked to me quite a couple of time: When to use I²R, V²/R or VI while calculating power? At first, the question looks simple and as if it needs no formal explanation but that's not the case. Use of any of them will give the correct result provided that you apply it correctly. Correct application is possible only when you understand the type of circuit you are dealing with. Another important point is to use the one which is going to take less time and help you calculate easily. All of the three equations tell the same thing but their usage is subject to the type of problem you're trying to solve. Let us understand when, how an what to use while calculating power in an electrical circuit.

Why earth pin in a 3 pin plug made thicker and longer than other 2?

-

We have been using various electrical appliances in our household having such socket plugs as shown above. The upper pin is called an earth pin while the lower two are live and Neutral. But have you ever wondered why the earth pin looks so different than the other two pins? If you had, here's the answer. An earth pin is used to discharge any electric current flowing through the metallic enclosure of an electric appliance due to some internal fault or loose connection to the earth. The current flowing through the metallic enclosure is taken up by an earth wire in the appliance and is sent to earth through the earth pin in the socket.  Now in no way, the earth pin should be inserted in live or neutral hole on the socket because in that case, current would flow through the earth pin to the appliance and also will result in burn-out as well as insulation breakdown. That's why, the earth pin is made thick or different in dimension than the other two pins so that ...

Working & Application of a Variable Voltage Variable Frequency Drive (VVVfD)

Variable Voltage Variable Frequency Drive (VVVfD) is one of the best and efficient methods of starting an Induction Motor Drive as well as it provides a smooth and wide range of Torque-Speed control. It saves electrical power and provides good motor starting and running characterstics. VVVfD controls the V/f (Volt/Hz) fraction to let the motor drive achieve good Torque-Speed characterstics as required. Hence it is also called, VSD - Variable Speed Drive or AFD - Adjustable Frequency Drive or Inverter based Drive as it uses Inverter to achieve the set points.  But how VVVfD works and why it is better than various other methods of Starting and Speed Control of Induction Motor based applications. Let's discuss the Theory, Working, Advantages and Applications of a VVVfD in detail.
