Six identical cells, each of e.m.f 2V are connected as shown above...

Six identical cells, each of e.m.f 2V are connected as shown above. The effective e.m.f of the cell is

A. 4V

B. 0V

C. 6V

D. 12V

QUICK ANSWER…

D

DETAILS…

Please note that in a series connection, effective voltage across cells equals the simple addition of each cell voltage. So, for these 6 identical cells of 2V each,

The effective e.m.f = 2V + 2V + 2V + 2V + 2V + 2V = 12V

Now for the right answer to the above question:

  1. Option A is incorrect.
  2. Option B is incorrect.
  3. C is incorrect. wrong.
  4. D is the correct answer.

KEY-POINTS…

You may please note these/this:

  • For series connection, effective voltage equals addition of all voltages involved.
  • For parallel connection, there is no effective voltage as same voltage is across all the terminals involved in this kind of connection.
