A conductor is a material through which an electric charge can move easily.
Is a battery a power source? True or false?
True
What type of circuit is it?
Simple circuit
It turns the electric current on or off. It is a simple mechanism that opens and closes a circuit.
Switch
It connects all the parts and sets a closed path between the poles of the shower source through which the current flows.
Wire
It's the power source of an electric circuit. It creates an electric current flows when the poles are connected through a conductor.
Battery
What happen when two objects have zero/neutral charge?
Two objects with zero net charge do not attract or repel each other.
All magnets have ______ opposite poles
Two
Name two magnetic materials
Iron, steel, cobalt, nickel
In a parallel circuit, there is more than one path for current to flow.... TRUE OR FALSE?
TRUE
What type of circuit is it?
Parallel circuit
What type of charge has the electrons got?
NEGATIVE
Complete the sentence. An object with an equal number of positive and negative charges……..
An object with an equal number of positive and negative charges has zero net charge. (We also say that the object is neutral).
When do two objects repel?
Two objects with the same charge repel each other.
It transforms the electrical energy flowing into another form of energy: light, heat, movement, sound, etc.
Load
Complete the sentence. We use electric circuits to transform ............
We use electric circuits to transform electrical energy into other useful forms of energy: light energy, thermal energy, mechanical energy, sound energy, etc
What's elecricity?
Electricity is the "flow" of electrons.
What's a insulator?
An insulator is a material through which an electric charge cannot move easily.
What parts has got an electrical circuit?
Power source, switch, wires and load
Is solid water insulator or conductor?
CONDUCTOR
What type of charge has the protons got?
POSITIVE
An object can have _______, ___________ or __________
An object can have positively charged, negatively charged, or zero net charge.
In a series circuit, there is only one path for current to go with three or more loads.
FALSE. In a series circuit, there is only one path for current to go with two or more loads.
In a simple circuit, there is only one path for current to go and only one load.... TRUE OR FALSE?
TRUE
What type of circuit is it?
Series circuit
Which part of a circuit conducts energy?
wires
What are the parts of an atom?
Protons, neutrons and electrons
What is the mission of the power source (battery)?
The power source (battery) creates an electric current flows when the poles are connected through a conductor.
Complete the sentence. An object is positively charged when it contains........
An object is positively when it contains more positive charges than negative charges. (More protons than electrons)
