What is Electricity?
Current or static charges.
Energy.
The flow of electrons.
All of them are right.
Static Electricity is:
The current that stays.
The negative or positive charges that stay.
Part of the Electricity from things.
It is charged materials that conducts electricity.
You can ________ a material with __________ Electricity by_____.
Charge/Static/ Friction.
Charge/Current/ Friction
Charge/Static/ Battery.
Change/Current/ Battery.
Natural Gas is:
Renewable
Non-renewable
(a) : the flow of electrons.
Hidroelectrical power is a: (a) energy source.
Similar _________ repel. Opposite charges __________. And ________ things are always ________ to charged things.
Charges/ Attract/ Neutral/ Repel.
Charges/ Repel/ Neutral/ Atracted.
Charges/ Attract/ Charged/ Atracted.
Charges/ Attract/ Neutral/ Atracted.
Eolic and solar power plants are: (a) sources.
(a) : is where electricity flows easily.
________ are great conductors, but there are materials, like ______ and plastic that are not good conductors. They are called _________.
Metals/ Wire/ Insulators.
Papers/ Rubber/ Insulators.
Metals/ Rubber/ Insulators.
Metals/ Rubber/ Renewable.
A Power source is:
Anything that can suply a circuit with electricity, like a battery or a power plant.
Anything that can produce electricity, like a battery or a power plant.
Anything that can store electricity, like a battery
Anything that can produce electricity, like a power plant.
To power an electrical device you need:
Wires, power source, switches and open circuit.
A conductor, a battery and an open circuit.
Conductors, energy source and a closed circuit.
Wires, battery a switch and a closed circuit.
This circuit is _______, because we _____________________.
Series/ can't turn on all light bulbs independently
Series/can turn on all light bulbs independently
Parallel/ can't turn on all light bulbs independently
Parallel/can turn on all light bulbs independently
Parallel circuits have
More wires and closed circuits in independent regions of the system.
Less wires and closed circuits in independent regions of the system.
More wires and closed circuits in one region of the system.
Lots of wires and lots of electrical devices in an open circuit.
In this circuit:
P.S - 3 points question.
The connections are series, the lamps are on, because the battery is powerful.
The connections are series, the lamps are off, because there is no power source.
The connections are parallel, the lamps are on, because there is no light switch.
The connections are series, the lamps are off, because the light switch is off.
The connections are series, the lamps are off, because the circuit is not closed.
Only one light bulb is on. Why?
Because the circuit is not closed. If the circuit closes, all light bulbs will be on.
Because the circuit is parallel and only one light switch is on.
Because there is no energy source for the second light bulb
Because the circuit is parrallel and all the switches are on.
Troubleshooting is:
The name we give to electrical devices problems.
When something is not working, that is what we call it.
The way we look into electrical problems.
All the others.
This is ________ because:
Working/ the circuit is closed.
Not working/ the circuit is closed.
Not working/ the circuit is not closed.
Working/ the circuit is not closed.
EXTRA (Hard level): In your house you have Alternated Current in__________ and Direct Current in _________. Examples of Alternated current are the _____ and the ______. Direct current can be __________
Transformers/ Devices/ The light poles/ the transformers' box/ Computer.
Boxes/ Batteries/ The washing machine/ Fridge/ Computer.
Transistors/ Devices/ The light poles/ the transform box/ Washing machine.
There are materials that are not conductors nor insulators, they are:
(EXTRA HARD QUESTION)
