The terminal voltage of the battery, whose emf is 10 V and internal resistance 1Ω1 \Omega, when connected through an external resistance of 4Ω4 \Omega as shown in the figure is: The terminal voltage of the battery, whose emf is 10 V and internal resistance 1 , when connected through an external

Options

  1. A6V
  2. B8V
  3. C10V
  4. D4V

Correct answer

B. 8V

Step-by-step solution

Current in circuit i=104+1=2Ai=\frac{10}{4+1}=2 \mathrm{ A} Terminal voltage =E−iR=10−2×1=8V\begin{aligned} \text{ Terminal voltage } & =E-i R \\ & =10-2 \times 1=8 \mathrm{ V} \end{aligned}$$
