Cells: EMF, Internal Resistance & Combinations

In an electric circuit shown, each cell has e.m.f. 2 V2\text{ V} and internal resistance 1 Ω1\ \Omega. The external resistance is 2 Ω2\ \Omega. The value of current (in A) is

Figure

Show answer and solution

Answer: (d)

  1. The figure shows three identical cells in series, all in the same direction.
  2. Enet=3×2=6 VE_{net} = 3 \times 2 = 6\text{ V}, rnet=3×1=3 Ωr_{net} = 3 \times 1 = 3\ \Omega
  3. I=62+3=1.2 AI = \frac{6}{2 + 3} = 1.2\text{ A}. So the answer is (d) 1.2.
