In a given time of `10s, 40` electrons pass from right to left. In the same interval of time `40` protons also pass from left to right. Is the average current zero? If not, the find the value of average current.

Explanation

To determine whether the average current is zero and to find its value, we can follow these steps:

### Step 1: Identify the charges involved
In the problem, we have:
- 40 electrons moving from right to left.
- 40 protons moving from left to right.

### Step 2: Understand the direction of current
