What happens when 1 coulomb of charge passes a point in 1 second?

When 1 coulomb of charge passes a point in 1 second, it defines a current of 1 ampere. The relationship between electric charge, current, and time is described by the formula:

[ I = \frac{Q}{t} ]

where ( I ) is the current in amperes, ( Q ) is the charge in coulombs, and ( t ) is the time in seconds. Plugging in the values from the scenario, if 1 coulomb of charge (Q) passes a point in 1 second (t), then:

[ I = \frac{1 \text{ coulomb}}{1 \text{ second}} = 1 \text{ ampere} ]

This current indicates that 1 coulomb of charge flowing past a point in a second is the very definition of 1 ampere, which is the standard unit for measuring electric current. Therefore, the statement accurately reflects the flow of current in the circuit under the given parameters.
