Electrical Energy
a form of energy that lets negatively charged particles move from one atom to another
What is electricity?
a material that lets electric current flow through it
What is a conductor?
a series of interconnected components that an electric current flows through to produce an effect such as light or sound
What is an electric circuit?
components that transport the electrical energy from the power source to the load device
What are conductors?
when the energy of the power source cannot reach the load device, so the electrical current cannot flow
What is an open circuit?
the flow of electrons from one atom to another inside a conductive material
What is electrical current?
a material that does not let electrical current flow through it
What is an insulator
components that receive the electrical energy from the power sources and convert it to other types of useful energy.
What is a load device?
componentd that supply the necessary electrical energy to the rest of the circuit in order to move the electrons
when the energy of the power source reaches the load devices, so the electric current flows
What is a closed circuit?
positively charged particles in an atom
What are protons?
A string-like object used in electrical installations that are generally made from copper and have a plastic casing around them for protection against electrical currents.
What are wires?
devices that regulate the circuit
What are control devices?
a component that converts electrical energy into light energy
What is a lamp?
when the electric current is transported by the wires without passing through a load device
What is a short circuit?
negatively charged particles in an atom
What are electrons?
a phenomenon caused by the accumulation of charge in a material
What is static?
a component that supplies electrical energy to the rest of the circuit
it has a positive and a negative terminal
What is a cell?
a load device that opposes the flow of electric current
What is a resistor?
The name for representing electrical circuits with a simple drawing.
What is an electrical schematic?
The component that causes the flow of electrons , such as a cell or battery
What is the power source?
The material that sparked the notion of static electricity in Ancient Greece. They noticed this material attracted other light-weight material when rubbed with a cloth.
What is amber?
a changeover switch
What is a two-way switch?
A button that opens or closes a circuit, but only if it is being pushed
What is a push switch?
the drawings that are commonly used by everyone to represent the components of a circuit
What are standardised symbols?
