alleryStart learning →A current of 1 A is defined as the flow of
A1 joule of energy per second
B1 volt of potential per second
C1 ohm of resistance per second
D1 coulomb of charge per second
Answer & Solution
Correct answer: D. 1 coulomb of charge per second
1. The chapter defines current as charge per unit time.
2. 1 A is 1 C of charge crossing a section in 1 s.
3. Volt is potential, ohm is resistance, joule is energy.
4. So option A is correct.
