Q3.2Multiple choice
Two batteries of emf ε1 and ε2 (ε2 > ε1) and internal resistances r 1 and r 2 respectively are connected in parallel as shown in Fig 3.1.
This question refers to a figure in the original PDF.
- (a)The equivalent emf εeq of the two cells is between ε1 and ε2, i.e. ε1< εeq < ε2. Fig 3.1 Current Electricity
- (b)The equivalent emf εeq is smaller than ε1 .
- (c)The εeq is given by εeq = ε1 + ε2 always.
- (d)εeq is independent of internal resistances r 1 and r 2.
