In a given time of `10s, 40s` 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: Understand the Problem
We have two types of charged particles moving in opposite directions: electrons moving from right to left and protons moving from left to right. We need to calculate the average current generated by both.

### Step 2: Identify Given Values
- Number of electrons (n_e) = 40
- Number of protons (n_p) = 40
