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

Answer & explanation

Correct answer: option 2

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.
