# Ohm's law

In this app, we will learn and explain the relationship between electric current, voltage, and resistance in a closed circuit. As a matter of fact, current, voltage, and resistance vary from circuit to circuit but there is often a simple relationship among them. This relationship is called Ohm’s law, which states, “At a constant temperature, the current flowing through the conductor is proportional to the applied voltage or potential difference across it”. Also, we will perform an experiment to verify this law.
This app also deals with ohmic as well as non-ohmic devices. For ohmic devices, the plot of current and voltage is a straight line indicating that the relationship between current and voltage is linear. For non-ohmic devices, the relationship is non-linear.
With this app are provided a quiz, key terms, the main image, and the links to other websites. This additional information helps to supplement our knowledge about the subject.
Through our visual-aid products, the learners are encouraged to examine, test, and revise their ideas about what science is and how it works. Our endeavour is to make them think like a scientist.
