If Q = net charge, t = time, then which of the following equations is correct ?

I = $\frac{Q}{t}$

The correct answer is option 2. I = $\frac{Q}{t}$.

The correct equation relating net charge (\(Q\)), time (\(t\)), and current (\(I\)) is \(I = \frac{Q}{t}\).

This equation represents Ohm's law, which states that the current (\(I\)) flowing through a conductor is directly proportional to the net charge (\(Q\)) passing through the conductor per unit of time (\(t\)). Mathematically, it is expressed as

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

This equation signifies that the current (\(I\)) is equal to the ratio of the net charge (\(Q\)) to the time (\(t\)) taken for that charge to pass through the conductor.
