Electron Flow | MCQs

Explanation

A circuit is a closed path through which electrons (electric current) flow.

It typically includes components like resistors, batteries, and wires, allowing controlled movement of current.

Explanation

A cathode ray is a stream of electrons that are emitted from a cathode (negative electrode) in a vacuum tube.

These electrons carry a negative charge, as they are negatively charged particles.

Explanation

A filament is a thin wire, typically made of tungsten, that is heated to produce a continuous flow of electrons.

When an electric current is passed through the filament, it heats up and releases electrons, creating a steady stream of electrons.

This principle is used in various devices such as vacuum tubes, cathode ray tubes (CRTs), and electron microscopes.
