MCQ
Which statement is wrong from the following?
  • A
    The earthing wire is green coloured
  • B
    In India, current flowing through wire is AC and its frequency is 50Hz
  • C
    In India, voltage between two wires is 110V
  • D
    T.V., tube light, bulbs are connected with 5A line
✓

Answer

  1. In India, voltage between two wires is 110V

Explanation:

In India, the voltage between two wires is 220V. So, C is wrong. All other statements are correct.
