What is the formula to calculate current (I) in terms of charge (Q) and time (s)?

• A. I = Q / T
• B. I = Q * T
• C. I = T / Q
• D. I = Q + T

Answer: (A)

The formula to calculate current (I) in terms of charge (Q) and time (T) is based on the definition of electric current, which is the rate of flow of electric charge. Current is defined as the amount of charge that flows through a conductor in a specific amount of time.

In mathematical terms, current (I) can be expressed as the total charge (Q) divided by the time (T) in seconds during which the charge flows. Therefore, the correct formula is I = Q / T. This relationship makes it clear that if you increase the amount of charge flowing in a given time, the current will increase, and conversely, for a fixed amount of charge, increasing the time will result in a lower current.

This fundamental understanding of current is crucial for students in electrical science, as it forms the basis for analyzing circuits and understanding how electrical systems operate.
