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.
An automobiel battery can explode. The battery emits a very small amount of Hydrogen gas which is highly flammable.
When electric current is passed through a conductor ,it becomes very hot and emits light. This is called the lighting effect of current.

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.
Your smoke detector emits a single beep to indicate a low battery or a malfunction.
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.
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.
