The statement 'If 1 coulomb flows past a point in 1 second, that is a flow rate of 1 ampere' is

• A. False
• B. True
• C. Not sure
• D. It depends

Answer: (B)

Electric current is the rate at which charge passes a point. The ampere is defined as one coulomb flowing per second. So if 1 coulomb passes in 1 second, the current is 1 ampere. This follows from I = Q/t, with Q = 1 C and t = 1 s giving I = 1 A. The statement is true because the definition directly matches this scenario. Saying it’s false, not sure, or depends wouldn’t fit since the relationship is a fixed definition for this case.
