alleryStart learning →A current of 3 amperes means charge passes a point at a rate of:
A3 coulombs per second
B3 joules per second
C3 volts per second
D3 ohms per second
Answer & Solution
Correct answer: A. 3 coulombs per second
1. The ampere is defined from charge and time.
2. Electric current is defined to be the rate at which charge flows.
3. An ampere is one coulomb per second.
4. So 3 amperes is 3 coulombs per second.
5. Joules per second would instead be power in watts.
