Choose the incorrect statementa)Flemings right-hand rule is a simple r...
Explanation:
The incorrect statement is option D: "In India, the AC changes direction after every 1/50 second."
Reason:
In India, the standard frequency of alternating current (AC) is 50 Hz. This means that the direction of current changes 50 times per second, not after every 1/50 second.
Details:
1. Direct Current (DC):
- Direct current (DC) is the flow of electric charge in a constant direction.
- It always flows in one direction, either positive or negative.
- DC is commonly produced by batteries, fuel cells, and solar cells.
- Examples of devices that use DC include mobile phones, laptops, and electric vehicles.
2. Alternating Current (AC):
- Alternating current (AC) is the flow of electric charge that periodically reverses direction.
- AC is the most commonly used form of electrical power worldwide.
- It is produced by generators and supplied through power grids to homes and industries.
- AC changes its direction back and forth at a specific frequency, measured in hertz (Hz).
- In most countries, including India, the standard frequency of AC is 50 Hz.
- This means that the current changes its direction 50 times per second.
3. Fleming's Right-Hand Rule:
- Fleming's right-hand rule is a simple rule used to determine the direction of induced current in a conductor.
- It states that if the thumb, forefinger, and middle finger of the right hand are held at right angles to each other:
- The forefinger points in the direction of the magnetic field.
- The middle finger points in the direction of the current.
- The thumb then points in the direction of the force experienced by the conductor due to the magnetic field.
4. Right-Hand Thumb Rule:
- The right-hand thumb rule is used to find the direction of magnetic fields due to current-carrying conductors.
- It states that if the right-hand thumb points in the direction of the current, the curled fingers represent the magnetic field lines around the conductor.
Conclusion:
The incorrect statement is option D, as the AC in India changes direction 50 times per second, not after every 1/50 second.
The incorrect statement is option D: "In India, the AC changes direction after every 1/50 second."

In India, the standard frequency of alternating current (AC) is 50 Hz. This means that the direction of current changes 50 times per second, not after every 1/50 second.

- The right-hand thumb rule is used to find the direction of magnetic fields due to current-carrying conductors.
- It states that if the right-hand thumb points in the direction of the current, the curled fingers represent the magnetic field lines around the conductor.
Conclusion:
The incorrect statement is option D, as the AC in India changes direction 50 times per second, not after every 1/50 second.
