The number of electrons striking the screen of CRT is `7.5xx10^(15)` in 10 s. Calculate the electric current.

Explanation

To calculate the electric current based on the number of electrons striking the screen of a CRT, we can follow these steps:

### Step 1: Identify the given values
- Number of electrons (n) = \(7.5 \times 10^{15}\)
- Time (t) = 10 seconds

### Step 2: Calculate the total charge (q)
The charge (q) can be calculated using the formula:
