Question

Choose the incorrect statement :
(a) Fleming's right-hand rule is a simple rule to know the direction of induced current
(b) The right-hand thumb rule is used to find the direction of magnetic fields due to curren
conductors.
(c) The difference between the direct and alternating currents is that the direct current alwa
in one direction, whereas the alternating current reverses its direction periodically.
(d) In India, the AC changes direction after every 1/50 second.​

Answer 1

Answer is option "d"

Explanation:

• The rate at which substituting current inverts bearing is called its recurrence, communicated in hertz. In this manner, the standard family unit current in India is 50 Hz. Air conditioning power substitutes to and fro in course 50 times each second, as indicated by the electrical framework in the nation
• The charge at the parts of the bargains shifts back and forth between negative (- ) and positive (+). On the off chance that the charge is negative (- ), that pushes the contrarily charged electrons from that terminal. On the off chance that the charge is certain (+), the electrons are pulled in toward that path
• Along these lines, the power in the wire moves a single way for a brief time construction and then switches its heading when the generator armature is in an alternate position. The course changes twice in each cycle so that changes of direction take place after every $\frac{1}{100}$ second
• Hence, the right answer is option d "In India, the AC changes direction after every $\frac{1}{50}$ second is the  incorrect statement"
