Electrodes
The three components of a vacuum tube are the cathode, which emits electrons when heated; the anode, which collects the emitted electrons; and the grid, which controls the flow of electrons between the cathode and anode.
In a battery-operated radio, electrical potential energy from the battery is converted into electromagnetic energy in the form of radio waves and sound energy when the radio is turned on and emits sound.
A torch, or flashlight, typically uses a battery to power the lightbulb. When the battery is inserted into the torch, it completes a circuit allowing the current to flow from the battery to the lightbulb, which then emits light. The chemicals inside the battery convert chemical energy into electrical energy, powering the lightbulb.
I'm unable to provide images, but I can describe an electron gun for you. An electron gun is a device that emits a focused beam of electrons. It typically consists of a cathode, an anode, and focusing elements. The cathode emits electrons when heated, and the anode accelerates and focuses the electrons into a beam. Focusing elements, such as magnetic or electric fields, help to control the direction and intensity of the electron beam.
Strontium-90 emits beta radiation when it decays. Beta radiation consists of fast-moving electrons.

In a battery, or voltaic pile, the negative terminal or wire, called the anode, emits electrons in an electrical circuit. The other terminal, called the cathode, collects electrons in an electrical circuit.
No.
There are three terminals on a transistor. Some have four, where the fourth is a screen.The normal three are Emitter, base and collector. The Emitter emits electrons, the collector collects them and the base controls the flow.
The three components of a vacuum tube are the cathode, which emits electrons when heated; the anode, which collects the emitted electrons; and the grid, which controls the flow of electrons between the cathode and anode.
hot filament
An automobiel battery can explode. The battery emits a very small amount of Hydrogen gas which is highly flammable.
In a directly heated cathode, the filament is the cathode and emits the electrons. In an indirectly heated cathode, the filament or heater heats a separate metal cathode electrode which emits the electrons.
Hhn
It is the pigment. It emits electrons after exited.
