La Ley de Ohm y la Intensidad de Corriente

La Ley de Ohm establece una relación entre tres elementos clave de los circuitos eléctricos: intensidad de corriente (I), voltaje (V) y resistencia (R). Esta relación se expresa mediante la fórmula V = I·R.

Cada elemento tiene su propia unidad de medida:

  • I = Corriente en amperios (A)
  • V = Voltaje en voltios (V)
  • R = Resistencia en ohmios (Ω)

Podemos despejar cualquiera de las tres variables según lo que necesitemos calcular:

  • Para calcular el voltaje: V = I·R
  • Para calcular la resistencia: R = V/I
  • Para calcular la corriente: I = V/R

💡 ¡Consejo útil! Imagina la electricidad como agua fluyendo por tubos. El voltaje sería como la presión del agua, la corriente sería la cantidad de agua que fluye, y la resistencia serían los obstáculos que dificultan el paso del agua.

Por ejemplo: Si tenemos un circuito con un voltaje de 30V y una resistencia de 10Ω, podemos calcular la corriente: I = V/R = 30V/10Ω = 3A (amperios)

Con esta fórmula podrás resolver problemas de circuitos como los mostrados en la actividad, donde necesitas encontrar valores desconocidos de corriente, voltaje o resistencia en cada situación.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
