Discharge doesn't take place at normal atmospheric pressure inside the cathode ray tube . Justify

Explanation

### Step-by-Step Solution:

1. **Understanding Cathode Ray Tubes (CRT)**:
- A cathode ray tube is a vacuum tube that contains two electrodes: a cathode (negative electrode) and an anode (positive electrode). When a high voltage is applied, electrons are emitted from the cathode and travel towards the anode.

2. **Role of Pressure in CRT**:
- For the discharge (flow of electrons) to occur, the space inside the CRT must be free of air or other gases. At normal atmospheric pressure, the presence of air molecules can interfere with the movement of electrons.
