Importance of Multilanguages In Professional Life

Cognitive Benefits :
Some research suggests that students who receive second language instruction are more creative and better at solving complex problems than those who do not. Other studies suggest that persons with full proficiency in more than one language (bilinguals) outperform similar monolingual persons on both verbal and nonverbal tests of intelligence, which raises the question of whether ability in more than one language enables individuals to achieve greater intellectual flexibility.

Health benefits of multilingualism and bilingualism:

Researcher Ellen Bialystok examined the effect of multilingualism on Alzheimer’s disease and found that it delays its onset by about 4 years. The researcher’s study found that those who spoke two or more languages showed symptoms of Alzheimer’s disease at a later time than speakers of a single language. Interestingly, the study found that the more languages the multilingual knows, the later the onset of Alzheimer’s disease.

Example of Voltage divider Rule

Firstly, I am explaining an example on VDR ( i.e. voltage divider rule ).
Determine voltage across R4 by voltage division rule. Assume V1 = 30V ,
 R1 =10 Ω , R2 =5Ω , R3 =10Ω , R4 = 5Ω

Solution:

          Here please note that you can not apply voltage division rule directly. That is
VR3 ≠   (R3/R1 + R3) V1 
Reason is that some current of R1 also passes through R2 and R3 so directly VDR cannot be applied. So to apply consider circuit as shown below

Now VR3  can be found  by VDR as
VR3 = (R3/R1 + R3) V1 

Kirchhoff’s Voltage Law

This rule states that,

” Sum of voltages around a loop is always equal to zero. “

Explanation:

its very simple law as described by given example.

Above example explains it in a well manner as to verify you apply loop analysis on

Kirchhoff’s Current Law

This rule states that,

“Net Sum of currents at a node is always equal to zero. “

or

“Current entering at a node is always equal to the current leaving from that node. “

Explanation:

its very simple law as described by given example.

I
As this rule says net current at a node  (i.e. junction of wires that

Thevenin’s Theorem

It states:

” Any combination of voltage sources, current sources and resistors with two terminals is electrically equivalent to a network of a single voltage source i.e. Thevenin voltage (Vth ) and a single series resister i.e. Thevenin resistance (Rth ). “

Explanation:

Vth is the open circuit voltage at the terminal where Thevenin’s equivalent is to be found.









Rth is the resistance at that terminal with all voltage sources replaced by short circuits and

Current Divider Rule

It go hand by hand with VDR (voltage divider rule. It is also easy in this rule current in series branch remains same whereas in parallel branch it is devided.

Explanation:

It is also very easy in a sense that you only have to remember that in series branch current always remains same but in parallel branch it divides through different elements.

As it is shown by a simple and clear example.

Here I is the total current that divides

Voltage Divider Rule

It is very easy rule in this you only have to remember one thing that in series branch voltage must be divided where as in parallel branch it remains same.

Explanation:

It is easy in a sense that you only have to remember that in parallel branch voltage always remains same but in series branch it divides across different elements.It can be remembered by a simple thinking that in cars or any other place where a battery requires it will be applied across terminals of a device so that full voltage can be applied on that device.From this simple example you can remember in parallel voltage remains same.

As it is shown by a simple and clear example.

Here E is the applied voltage source across a simple linear circuit which consists
