Question

There are six identical cells each cell having an electromotive force (emf) of $ 6\,\,volt $ , which are joined in parallel. Then the resultant emf of the combination will be

• A. $ 13\,\,V $
• B. $ \frac{1}{6}V $
• C. $ 12\,\,V $
• D. $ 6\,\,V $

Answer 1

Answer: (D)

Number of cells $ =6 $ Emf of each cell $ =6\,\,volt $ All the cells are connected in parallel. In parallel combination the emf of all cells remains constant. Hence, emf of the combination is $ 6\,\,volt $ .
