What is the formula for average current if the charge is known?

• A. I = Q*t
• B. I = Q/s
• C. I = s/Q
• D. I = Q*t²

Answer: (B)

The average current can be calculated using the relationship between charge, current, and time. Current (I) is defined as the rate of flow of charge over time. When the total charge (Q) that flows through a conductor over a certain time period (t) is known, the average current can be expressed using the formula I = Q/t. In the context of the choices given, the correct representation of this formula can also be seen in terms of the variables. The choice that states I = Q/s, where 's' represents time in this context, is a rephrasing of the formula where 's' is used instead of 't' to denote time. Since current is the charge per unit time, understanding that I = Q/t is foundational to electrical concepts. This formula highlights how current is directly proportional to the charge and inversely proportional to the time, making it crucial for understanding electrical circuits and systems.
