Hi Mr Electro family!! This is an educational website for electrical stream ( Electrical engineering, Diploma student and PreDiploma students) . This is mainly focused for those students who are waiting for Government jobs like LokSewa Aayog PSC, NEA, CANN NTC for level 3, level 4, level 5 and level 7 and also private jobs.

    1. Sir you can check how many right answer you have done for now date... We will going developing for other features.

    2. Now you can find answer after your answer submit. Thanks for improving us....

  2. How can we check our answers ???

    1. Now you can find answer after your answer submit. Thanks for improving us....

  3. How to get results

    1. Hi sir/madam, after you submit your answer, you will get your marks by pop up dialogue box and answer list of all question.

  4. 12 no question is wrong . There correct answer is d)can be connected in series only.

    1. sir, When we connect two batteries with different emfs together in parallel they will act as a short circuit. so can not connect in parallel is more convenient option. And we can connect batteries series and parallel combined circuit also so it is less convenient option.
