CONVERTING ELECTRICAL ENERGY
Heat: Thermoelectric generators are solid state devices that convert heat directly into electricity,
Motion: We convert rotating energy into electricity by spinning magnets within large could of wire.
Light: converted into electrical energy through the photovoltaic effect in solar cells.
Sound: converted into other forms of energy, such as mechanical energy and electrical energy.
ENERGY AND THE ENVIROMENT :
Environmental impact of energy production and transmission
The use of renowable energies
Responsible use of electrical energy:
Save energy
Open circuits and closed circuits. Short circuits.
Resistance is the measure of opposition to electric current.
A short circuit is an electric circuit offering little or no resistance to the flow of current.
Main electric variables.Ohm`s law
The main electric variables are:
Current
Voltage
Resistance
REPRESENTING CIRCUITS: ELECTRICAL SCHEMATICS
fundamental two-dimensional circuit representation showing the functionality and connectivity between different electrical components
TYPES OF CIRCUITS: SERIES, PARALLEL AND SERIES-PARALLEL COMBINATION
Circuits can have diferent characteristics depending on how we arrange the load devices.
PARALLEL CIRCUITS
SERIES PARALLEL COMBINATION CIRCUITS
SERIES CIRCUITS
SOLVING CIRCUITS:
the fundamental laws, using the node voltage method or the mesh current method.
SOLVING SERIES CIRCUITS:
CURRENTS
It = I1 = I2 =... = In
VOLTAGES:
Vt= V1 + V2 +... + Vn
RESISTANCES :
Rt= R1 + R2 +...+ Rn
SOLVING PARALLEL CIRCUITS
CURRENTS:
It = I1 = I2 =... = In
VOLTAGES:
Vt= V1 + V2 +... + Vn
RESISTANCES:
1/Rt = 1/R1 + 1/R2 +... + 1/Rn
