As a result, the free electrons lose electrical energy and the metal ions gain energy. This causes them to vibrate faster and with bigger amplitude – which means a higher temperature.

There are many laws in physics, science and nature, and Ohm’s Law is one of the most important in understanding basic ...

The symbol for resistance is R, it is measured in ohms \((\Omega )\). The symbol for current is I, it is measured in amperes \((A)\).

This course introduces the basic principles of electrical engineering, including the concepts of voltage, current, resistance, inductance and capacitance. Ohm's Law, Kirchhoff's Laws, superposition, ...
