Combination of Cells
Combination of Cells
To increase the potential difference or the time of flow of current cells are used in combination. There are two types of combinations
1. Series Combination
2. Parallel Combination
Series Combination:
In this combination the positive terminal of one cell is connected to the negative terminal of the second cell and the positive terminal of second cell is connected to the negative terminal of the third cell and the process continues. In this type of combination the resultant potential difference is equal to the sum of potential difference of the individual cells. This type of arrangement is used to increase the potential difference.
In the series combination if V1, V2, V3 are the potential difference of each cell then the resultant potential difference V is given by the formula
V= V1 + V2 + V3
This can be applied to any number of cells.
Parallel Combination:
In this combination the positive terminal of one cell is connected to the positive terminal of the second cell and the negative terminal of one cell is connected to the negative terminal of the other cell and the process continues. In this type of combination the resultant potential difference is equal to the potential difference of the individual cells but the time for which the current will flow through the circuit increases. This type of arrangement is used to increase the time duration of the circuit.
In the series combination if V1, V2, V3 are the potential difference of each cell then the resultant potential difference V is given by the formula
V = V1 = V2 = V3
This can be applied to any number of cells.

Students / Parents Reviews [10]
My experience was very good with Abhyas academy. I am studying here from 6th class and I am satisfied by its results in my life. I improved a lot here ahead of school syllabus.

8thIt was a good experience with Abhyas Academy. I even faced problems in starting but slowly and steadily overcomed. Especially reasoning classes helped me a lot.
Cheshta
10thIt was good as the experience because as we had come here we had been improved in a such envirnment created here.Extra is taught which is beneficial for future.
Eshan Arora
8thOne of the best institutes to develope a child interest in studies.Provides SST and English knowledge also unlike other institutes. Teachers are co operative and friendly online tests andPPT develope practical knowledge also.
Aman Kumar Shrivastava
10thAbhyas is a complete education Institute. Here extreme care is taken by teacher with the help of regular exam. Extra classes also conducted by the institute, if the student is weak.

10thA marvelous experience with Abhyas. I am glad to share that my ward has achieved more than enough at the Ambala ABHYAS centre. Years have passed on and more and more he has gained. May the centre flourish and develop day by day by the grace of God.

7thBeing a parent, I saw my daughter improvement in her studies by seeing a good result in all day to day compititive exam TMO, NSO, IEO etc and as well as studies. I have got a fruitful result from my daughter.
Prisha Gupta
8thAbhyas Methodology is very good. It is based on according to student and each child manages accordingly to its properly. Methodology has improved the abilities of students to shine them in future.
Manish Kumar
10thMy experience with Abhyas academy is very good. I did not think that my every subject coming here will be so strong. The main thing is that the online tests had made me learn here more things.

8thAbout Abhyas metholodology the teachers are very nice and hardworking toward students.The Centre Head Mrs Anu Sethi is also a brilliant teacher.Abhyas has taught me how to overcome problems and has always taken my doubts and suppoeted me.
