Question

In each of the following questions, match column I and column II and select the correct match out of the four given choices.

Column I	Column II
(a) The series combination of cells is for	(p) More current
(b) The parallel combination of cell is for	(q) More voltage
(c) In series combination of n cells, each of emf ε the effective voltage is	(r) ε
(d) In parallel combination of n cells, each of emf ε the effective voltage is	(s) nε

(A) a – p, b – q, c – r, d – s 

(B) a – q, b – p, c – r, d – s 

(C) a – q, b – p, c – s, d – r 

(D) a – p, b – q, c – s, d – r

Answer 1

The correct option  (C) a – q, b – p, c – s, d – r

Explanation:

(1) in series combination, voltage increases, current is same 

(2) in parallel combination, voltage is same, current increases 

(3) Effective voltage for series combination of n cell = nE 

(4) for parallel combination voltage remaining same = E
