Circuit whit multiples control devices
CIRCUITS
Closed crcuits
The electric current does not flow
Open circuits
The electric current flow and reaches the lamp to light it
SHORT CIRCUITS
Parallel cirrcuits
In these circuits, the load deices are conected on differents branches of the wire. There are several possible paths for the electric current to flow through.
Series circuits
In these circuits, all the components are conected one after the other. Thid way, all the current flows through all the load devices. There is only one possible path for the electric current to flow through
MAIN ELECTRIC VARIABLES :check:
Voltage (V)
This is the difference in the charge between two pints, which makes the electrons move.
Resistance (R)
This is the opposition to the flow of the electron current.
Current (I)
This is the intensity of the current of electrons flowing throught a conductor over a certine time
ELECTRICAL ENERGY
:check:
Heat
When electrons move throught a conductor, they create fiction and prduce heat.
Motion
We can convert electricity to motion using a motor. the effect obtain when we make an electric current flow throught motor its turn ina rotary motion.
Light
We can convert electricity to light throught load devices
Sound
We use electrical energy to transmit sounds throught microscophes and we can produce sound effect throught sirens... .
