This document defines several key electrical components: resistance measures an object's opposition to current flow; light bulbs produce light by heating a filament; batteries store electrical energy; screens display computer processing results; transistors amplify, oscillate, switch or rectify signals; and capacitors passively store energy and sustain electric fields.

1. Resistance
The electrical resistance of a object is a measure of its opposition to the
flow of current.

2. Light Bulb
Electrical device that produces light by heating a metal
filament.

3. Battery
Device that stores electrical energy.

4. Screen
It is a display that shows the user the results of processing
a computer via an interface.

5. Transistor
Semiconductor electronic device which serves as the
amplifier, oscillator, switch, or rectifier.

6. Capacitor
Passive device, used in electricity and electronics, energy
storage capable of sustaining an electric field.
