A day in the life of an Engineering Student

That is how your life runs as an Engineer. Back to business after this.

Have a great Week.

Person or Human

I wonder what is the difference between being a person and being human.

This leaves us wondering. Check the next post to see what your life is all about if you are an Engineer.

No Rest for Engineers

Just to start the week on a light note, check these pictures.
We are continuing with our lessons after this.

When an Engineer thinks he is relaxing, he realizes that in fact he is still working. Check the next post.

Engineering Jokes for the weekend.

Till Monday.

Series-Parallel Magnetic circuit

Below is an example which shows that you can treat magnetic circuits in exactly the same way that you treat electric circuits. The components that are related are shown below:

Magnetomotive force is the driving force in a magnetic circuit. It is analogous to the electromotive force in the electric circuit.

The reluctance in the magnetic circuit is the opposition to the establishment of flux hence is analogous to resistance in the electric circuit.

The flux in the magnetic circuit is the effect of the mmf and hence is analogous to the current.

Basic Formulae used in Electrical Circuits

Below are the basic formulae which an Electrical or Electronic Engineer should know in order to be able to deal with electrical circuits. Some may use them just to pass tests, some to analyse circuits and at a higher level you need them to design circuits.

They should be know and not memorized to avoid confusion.

THEVENIN'S THEOREM EXPLAINED BY EXAMPLE

Thevenin’s theorem states that a linear two-terminal circuit can be replaced by an equivalent circuit consisting of a voltage source V_Th in series with a resistor R_Th , where V_Th is the open-circuit voltage at the terminals and  R_This the input or equivalent resistance at the terminals when the independent sources are removed.

The method of removing sources has been described in Norton's Theorem. The steps for getting the Thevenin equivalent resistant is again the same as the process for getting Norton's equivalent resistance. The method for getting the Thevenin's equivalent voltage will be described in the example below..

Qn. Find the Thevenin Equivalent Circuit across A-B and determine the load current.
