3 input Adder circuit using OPAMP IC 741

Asable Multivibrator using IC 555


_*Benefits of Bifocal Electronics at Std XI ,XII.*_

* Increases Avg.%. Out of 200 Marks,100 for Practical.

* Exemption from 2 Subj. language-II & Biology or other Subject.

* Helpful for Std XII Physics, MH-CET, IIT,  Degree & Dip Engg subjects.

* Eligible for B.E., B.Arch,B.Pharm,B.Sc (CS,IT)

* Direct admission to 2nd Yr of 3 yrs Diploma.

_____________-----________

 *Advantages of Electronics over C.S at Std XI , XII level.*

* Electronics curriculum was almost same in past and will be same in future for many years.

>In CS there are continuously updates. What u learn today will be obsolete tomorrow or hardly be useful.

** Electronics subject

is more helpful than CS to score high marks in Physics, MH-CET, IIT Mains....

* Electronics is mainly  hardware oriented. Also interesting. Hence you can construct your circuits, you can repair most of the electrical & electronics gadgets in your home with minor problems. Once expertize you can repair appliances with major faults.

> CS is mainly Software oriented.Hence it helps in developing softwares.

* Electronics students can also enter in to IT field.
