Demostración de clases de carga por frotación en varillas

Principle

The students should see that on rubbing different materials a negative or a positive charging results that can be demonstrated with a neon tube.

Benefits

  • Quick and easy experiment for qualitatively understanding of electrostatic phenomena

Tasks

What can we demonstrate ...

Demostración de clases de carga en láminas y placas

Principle

The pupils see that two isolators, made of different materials, are differenly charged when rubbed. They are able to determine the type of charge with a neon tube or an "electrical balance". They trace back the charging up to a seperation of charge.

Benefits

  • Quick and easy ...

Fuerzas entre cuerpos eléctricamente cargados

Principle

The pupils learn that, between two electrically-charged bodies, forces act. These are repelling forces when both bodies are identically electrically charged and forces of attraction when they are oppositely charged.

Benefits

  • Quick and easy experiment for qualitatively ...

Modelo de electroscopio

Principle

The pupils learn how an electroscope works, using a simple model, and are able to demonstrate electrical charges.

Benefits

  • Quick and easy experiment for qualitatively understanding of electrostatic phenomena

Tasks

We construct an electroscope. Construct a model of an ...

Funcionamiento de electroscopio

Principle

The pupils should recognize

  • that one can demonstrate electrical charging with an electroscope but that the type of charge is not revealed,
  • that from the extent of pointer swing the strength of the charge can be inferred,
  • that using a known polarity of charge on the ...

Inducción electrostática en conductores y no conductores

Principle

The pupils observe the effect of a force between charged bodies and uncharged conductors and non-conductors and they can explain the observed phenomena. They also observe with two uncharged bodies that forces of electrostatic induction can arise from a charged ...

Efecto de fuerza de inducción electrostática (carga de ima- gen)

Principle

The pupils should learn that between an electrically charged insulator and an uncharged electrical conductor an electrical force of attraction can also arise. The forces are of the same type as those with differently charged insulators but they can only be explained by a shifting of ...

Inducción electrostática con electroscopio

Principle

The students apply their knowledge of electrostatic induction to the electroscope. They recognize why a pointer deflection can appear even as a charged object approaches the electroscope. They can explain the series of events in the electroscope.

Benefits

  • Quick and easy ...

Conductores como acumuladores de carga

Principle

The pupils should come to realise that metal objects such as an electroscope, induction plate and Faraday-beaker can store charges and can also transport them. They should observe that the amount of stored charge depends on the size and shape of the body.

Benefits

  • Quick and ...

Distribución de carga en copa de Faraday

Principle

The pupils observe that when a Faraday-beaker is charged up the charges are located on the outside of the beaker and can only be removed from there. Nevertheless, charges can equally well be applied to the inside as to the outside of the beaker.

Benefits

  • Quick and easy ...

Acumulación de cargas positivas y negativas

Principle

The pupils observe that when a Faraday-beaker is charged up the charges are located on the outside of the beaker and can only be removed from there. Nevertheless, charges can equally well be applied to the inside as to the outside of the beaker.

Transporte de cargas a través de un péndulo

Principle

The students learn that a metallic pendulum can independently transport charges so that at least one body is partly discharged.

Benefits

  • Quick and easy experiment for qualitatively understanding of electrostatic phenomena

Tasks

A pendulum transports charges. Show that ...

Movilidad de cargas en aislantes y en conductores

Principle

The pupils learn that in insulators charges are locally bound but in metals, that is conductors, they are free to move.

Benefits

  • Quick and easy experiment for qualitatively understanding of electrostatic phenomena

Tasks

Can the charges in bodies be shifted? ...
