100
the amount of charges that goes through a conductor per time unit (measured in Ampere)
Intensity
100
components of an electric circuit
generator, wire conductor, switch, receptor

Define Electrical connections and list its types of connections
The behavior of electric elements depends on how they connect to each other.
Series connection, Parallel connection, Combination circuits
100
This measuring instrument measures the electrical voltage and it must be connected in parallel
Its symbol is:
Voltmeter
100
What is Electric Power measured in
Watts
200
the energy per charge unit that makes them flow through material (measured in Volts)
voltage
200
Define Generator and the types of generators
provides the energy necessary to move the electrons; it produces a continuous electric current.
batteries, alternators or dynamos, photovoltaic solar cells, hydrogen cells
200
Define Series Connection and its characteristics
The series circuit connects the electric elements one behind the other. There is only one connection point between elements and nothing else connected there.
All the lamps are in line, so intensity is the same for all of them.
200
This measuring instrument measures the electrical intensity and it must be connected in series
Its symbol is:
ammeter
200
General formula for Electric power
P = V· I
300
the opposition to the movement of the charges through a conductor (measured in Ohms)
electric resistance
300
Define recepetor and name the types
They are the components that transform electrical energy into another type of energy.
Resistors, bulbs, motors and bells.
300
Define parallel connection and its characteristics relating to voltage and intensity
All the elements are connected by two points.
Voltage is the same in all elements, so all the lamps have the same energy and the light is higher.
Intensity is distributed between elements, but all of them have the same voltage. That is the reason why they have the same energy for each lamp, so the light is the same.
300
This measuring instrument measures the electrical resistance. The measured resistance must be connected to nothing, but this measuring instrument
Its symbol is:
Ohmmeter
400
V=IR (voltage = current x resistance)
Ohm's Law
400
Purpose of Control Componentes and list the types.
They are used to rule an electric circuit
Switch, push button and changeover switch.
400
In what type of circuit is the equivalent resistance in a circuit like this is found by reducing the different series and parallel combinations step-by-step to end up with a single equivalent resistance for the circuit.
Combination circuit
400
This measuring instrument measures different electrical magnitudes using the rotating dial and different connectors.
multimeter
500
Purpose of Protection components and the function of a fuse.
They stop the current when is too high so that the important components of the circuit are not damaged
It is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current. It is a sacrificial device; once a fuse has operated it is an open circuit, and must be replaced.
