ELECTRICITY
Electric circuite
Elements
Receivers: transform electric energy into useable energy (Motor, light bulb...)
Control elements (switch, push button...)
-
Protection elements (fuses, breaker switches, earth-leakage circuit breakers)
-
-
Types
-
Parallel circuit: The potential difference of each element is the same, but the current that flows through each branch is different
Mixed Circuit: lnvanably, they maintain the current that flows through the elements in senes, and the voltage of the elements in parallel.
Electric current
-
Effects
-
Electromagnestism: When the electnc circuit closes, lt's transformed mto a magnet and it creates a magnetic field.
Heat: The movement of electrons in a cable causes continuous collisions and an increase in the temperature of the cable
Electric magnitudes
-
Electric current: Number of electrons, that flows through a
conductor per second. It is measured in amperes.
V = I*R
