Residual current circuit breaker (RCCB)
The residual current circuit breaker (RCCB) is one of the elements of a consumer unit. The following visual explains its function.

Representative value
The representative value of a series of measurements is the one which we think is closest to the real value of the said measurement.

Representation of forces
Forces are represented by means of vectors. A vector is an oriented sector. The following animation representes the characteristics of a vector.

Renewable energy sources
Renewable energy sources are those which after being used can be regenerated naturally or artificially. The following pictures are graphic examples rof enewable energy sources.

Relativistic paradox
If at relativistic speeds bodies decrease in length, would it be possible to shut a large rocket which was travelling at the speed of light in a hangar? The answer to this question constitutes a "relativistic paradox".

Relative movement of the Earth
The educational resource shows a visual about the relative movement of the Earth: our planet is enormous compared to a train, which is why although all the earth moves, it seems to us to be still, and the sky around it the one that moves.

Relative error
The relative error of a measurement is the quotient between the absolute error of the measurement and its real value.

Refraction
Imagine that a wave passes from a deeper zone to another shallow zone, or vice versa. There will be refraction.

Radians: what are they?
Angles can be measured with sexagesimal degrees. A right angle is equal to 90 degrees. Radians are another way of measuring angles.

Radioactive constant
The radioactive constant or decay constant, is a coefficient of proportionality which relates the atoms which disappear in a period of time t, with the initial atoms for each radioactive nuclide.
Contexto educativoTipo de recursoColecciones -
Radioactive equilibrium
The activities of the isotopes formed at each stage of the radioactive series are equal to each other after some time. It is then said that radioactive equilibrium has been reached.
Contexto educativoTipo de recursoColecciones -
Radioactive particles
Radiation emitted by radioactive bodies.The radiation emitted by radioactive substances behaves differently when it passes through electric and magnetic fields.
Contexto educativoTipo de recursoColecciones -
Radioactivity
The activity of a sample of a radioactive substance is the number of nuclei which disappear per unit of time and represents the speed of decay.

Radiant energy
Radiant energy is what is possessed by electromagnetic waves like visible light, radio waves, ultraviolet rays (UV), infrared rays (IR), etc. The following animation describes the existing types of radiation.

Quantum tunnelling
If we had particles between two barriers of potential, but of finite size, there could be diffraction on the other side of the barrier; this phenomenon is called the tunnelling effect.
Contexto educativoTipo de recursoColecciones -
Quantum potential well
We cannot give any value to the energy of the particle. Its wavelength must "fit" in the well, the same way the harmonics of the musical notes on a guitar must adjust to the length of their strings.

Quantum atom
Electron in quantum atom (atomic orbitals).
