While performing cathode ray experiment. It is nothing to do as why cathode is connected to negative terminal of the battery 🔋. They just connected one plate with negative terminal of the battery & one plate with +ve terminal of the battery.
Cathode rays are so named because they are emitted by the negative electrode, or cathode, in a vacuum tube.
