In the circuit diagram shown in Figure, the potentials of the points $\mathrm{B},\mathrm{ }\mathrm{C}$ and $\mathrm{D}$ are respectively-

• A

  $\mathrm{12 }\mathrm{V},\mathrm{ }\mathrm{10 }\mathrm{V},\mathrm{ }\mathrm{6 }\mathrm{V}$
• Correct answer
  B

  $\mathrm{11 }\mathrm{V},\mathrm{ }\mathrm{9 }\mathrm{V},\mathrm{ }\mathrm{6 }\mathrm{V}$
• C

  $\mathrm{11 }\mathrm{V},\mathrm{ }\mathrm{9 }\mathrm{V},\mathrm{ }\mathrm{0 }\mathrm{V}$
• D

  $\mathrm{12 }\mathrm{V},\mathrm{ }\mathrm{10 }\mathrm{V},\mathrm{ }\mathrm{0 }\mathrm{V}$

Solution

According to Kirchhoff's Voltage Law in loop ABCDA, Current flowing in the circuit is 1A

Hence, the correct answer is option: 'B'.
