- 1 ampere is defined as the amount of current that flows when 1 coulomb (C) of charge passes a point in 1 second (s).
- The formula for current (I) is given by I = Q / t, where 'I' is the current in amperes, 'Q' is the charge in coulombs, and 't' is the time in seconds.
- According to the options provided, Option 2: A = 1C/s correctly represents this relationship.
- This definition is fundamental in the field of electromagnetism and is used to standardize measurements of electric current.
Additional Information
- The ampere is one of the seven base units in the International System of Units (SI).
- It is named after the French physicist André-Marie Ampère, who is considered one of the founders of the science of electromagnetism.
- The ampere is a crucial unit in electrical and electronic engineering, affecting everything from circuit design to power distribution.
- Modern definitions of units like the ampere rely on fundamental physical constants, ensuring consistency and precision in scientific measurements.
