Charge, current and circuits
I am negatively charged and located in the shell of the atom.
What is an electron?
I'm generated by motors, transforming electrical energy into mechanical energy.
What is motion?
I'm the unit of voltage in the International System of Units.
What is an Ohm?
There is a value for current of 25 A and a value for resistance of 20 Ω. What's the value of the voltage?
500 V
I don't allow the electrons to pass through me.
What is an insulator?
I'm used to generate heat.
What is a resistor?
I'm the opposition of the eletric current.
What is resistance?
There is a value for current of 20 A and a value for voltage of 120. What's the value of the resistance?
6 Ω
I transform electrical energy into another type of useful energy.
What is a receptor?
I'm the abbreviation of Light-Emitting Diode.
What is a LED?
To measure me, I use an ammeter.
What is the electrical current?
For the same value of resistance, what happens with the voltage if we double the current?
The current will double too.
I'm used to alternate the current between two circuits.
What is a 3-way switch?
I'm generated due to collisions of atoms of the material I'm flowing through.
What's the heat?
I'm the difference between electrical energy at two points of the circuit.
What is voltage?
What happen if we put a voltimeter in series?
The measure provided by the voltimeter will be 0.
I use a chemical reaction to generate electric current
What is an hydrogen cell?
My temperature goes so high that i'm turning red!
What is incandescence?
I must always be connected in parallel in an electric circuit.
What is a voltimeter?
What happen if we put an ammeter in parallel?
The current flowing through the ammeter would be really high.
