๐๐ญ๐๐ญ๐ข๐ ๐๐ฅ๐๐๐ญ๐ซ๐ข๐๐ข๐ญ๐ฒ --> is a phenomenon caused by he accumulation of charge in a material, electric current is realated to moving charges.
๐๐ฅ๐๐๐ญ๐ซ๐ข๐๐๐ฅ ๐๐ง๐๐ซ๐ ๐ฒ! --> is the most common form of energy because it is easy to obtain, it can be transported over long distances and it can easily be transformed into many other forms of energy (light, heat, sound and motion!)
Electric Circuits --> is a series of intercomected componets that an electric current flows through to produce an effect -> examples: light, heat, sounds or motion.
๐๐ฅ๐๐๐ญ๐ซ๐ข๐๐ข๐ญ๐ฒ! --> is a form of energy that lets negatively charged particles (electrons) move from one atom to another.
๐๐ฅ๐๐๐ญ๐ซ๐ข๐ ๐๐ฎ๐ซ๐ซ๐๐ง๐ญ --> is the flow of electrons from one atom to anther inside a conductive materia
๐๐จ๐ง๐๐ฎ๐๐ญ๐จ๐ซ๐ฌ ๐๐ง๐ ๐๐ง๐ฌ๐ฎ๐ฅ๐๐ญ๐จ๐ซ๐ฌ --> materials that electric curren flow throught them for example:
Conductors: Gold, silver, aluminium, and copper
Insulators: Wood, plastic and cardboard
COMPONENTS OF A CIRCUIT-->
LOAD DEVICES
POWER SOURCES-->
Cell--> Supplies electrical energy to the rest of the circuit. Battery--> A grouped set of cells.
Lamp--> Converts electrical energy to light energy. Motor--> Converts electrical energy to kinetic energy.
Buzzer: converts electrical energy to sound energy.
Resistor: opposes the flow of the electric current.๐
CONDUCTORS
Wire: the component that electric current flows through ๐
CONTROL DEVICES:
One-way switch โฟ: open or close the circuit when they are pressed.
push switch: open and close the circuit but only while the button is pushed ๐คฐ๐ฟ
two-way S.W.I.T.C.H: change from one position to the other โค๏ธ๐.
Open circuit off: the lamp is not lit
closed circuit on: the lamp is lit
short circuits when the electric current is transported by the wires without passin through a load device,
main electric variables:
current
voltage
resistance:
Ohmยดs law: the current is directly proportional to the electric potential difference
