What formula represents the relationship between current, charge, and time?

I=Q/T
V=I*R
P=V*I
R=V/I

The correct answer is: I=Q/T

The formula that represents the relationship between current, charge, and time is articulated as I = Q/T, where I stands for current, Q represents charge, and T denotes time. This equation essentially defines current as the rate at which electric charge flows. In more detail, current (measured in amperes) is calculated by dividing the total charge (measured in coulombs) that has passed through a conductor by the time (measured in seconds) it takes for that charge to flow. This fundamental relationship is crucial in understanding how electric circuits operate and is a foundational concept in the study of electrical engineering and physics. The other formulas relate to different electrical concepts: V = I * R describes Ohm's Law, which illustrates the relationship between voltage, current, and resistance; P = V * I shows how electrical power is calculated using voltage and current; and R = V/I represents the calculation of resistance from voltage and current. While all these formulas are significant in their own right, they do not pertain to the specific relationship between current, charge, and time as described by the correct answer.
