AI Generated Solution

To solve the problem, we need to determine the number of electrons flowing through a conductor when a potential difference is applied across it. We can follow these steps: ### Step 1: Calculate the Current (I) Using Ohm's Law, the current (I) flowing through the conductor can be calculated using the formula: \[ I = \frac{V}{R} \] where: - \( V = 3V \) (potential difference) - \( R = 1.5 \Omega \) (resistance) ...
