If you rub a pen on a piece of cloth and place it next to small pieces of paper what will happen?
The bits of paper will be attracted to the pen.
What is the manifestation of energy associated with electrical charges both at rest and in movement called?
Electrical Energy or Electricty.
Name 2 sources electricity can be obtained from.
petroleum, wind, sun or water.
The most commonly used form of energy in society?
Electricity
3 forms of energy electricity can be transformed into:
Luminous, Heat and Mechanical energy
What does a continual movement of electrical charges through conductive materials create?
Electrical Current
A set of elements connected to one another so an electrical current can circulate through them.
Electrical Circuit.
Name the components of an electrical circuit.
Power Source, Load, Conductors.
This is the device from which the circulating electrical current originates.
Power Source
Name 2 generators that are used to make different electrical circuits work.
Batteries, Accumulators,Alternators, Dynamos.
The device that transforms electrical energy into another form of energy.
Load.
The cables or wires that connect the power source to the load.
Conductor.
Two types of components used to control and protect circuits.
Control and Protective Device.
Loads can be connected in 3 different ways:
Series, Parallel, Combined Circuits.
A circuit that has different loads located one after another so that the same electrical current circulates to them sequentially:
Series Connections
In most electrical installations the loads are connected parallel, why?
It allows them to work with tha same voltage and if any one of them breaks the others continue to operate.
