The correct relationship between charge, current, and time is expressed in the formula Charge = Current x Time. This equation reflects the fundamental connection between these quantities in electrical circuits.

In this context, charge refers to the amount of electricity transferred in a circuit, current represents the flow rate of electric charge, and time is the duration for which the current flows. When current (measured in amperes) flows through a conductor for a certain period (measured in seconds), it results in a specific total charge (measured in coulombs) being transferred.

For example, if a current of 2 amperes flows for 3 seconds, the total charge moved would be calculated as follows: Charge = 2 A x 3 s, which equals 6 coulombs. This relationship is crucial for understanding how electric circuits operate and for calculating various electrical parameters in practical applications.

The other options suggest incorrect mathematical relationships that do not accurately represent how charge, current, and time interact. The formula is a direct multiplication of current and time to yield charge, which is why this particular formulation is the correct one.
