Ohms Law Explained. In this video we take a look at Ohms law to understand how it works and how to use it. We look at voltage, current, resistance and the relationship between these. We also use ohms triangle to solve examples.

This electronics video tutorial provides a basic introduction into ohms law. It explains how to apply ohm's law in a series circuit and in a parallel circuit.

Ohms law is one of the most important laws governing electrical and electronic technology. It is used in electrical and electronic circuit design. Aspects of Ohm's law include the formulas, calculations, Ohm's Law triangle and aspects of Ohmic and Non-Ohmic conductors. These are all covered in the video which is aimed at STEM learning / STEM education, etc.

Ohms law states that the current flowing in a circuit is directly proportional to the applied potential difference and inversely proportional to the resistance in the circuit.

In other words, this means that by doubling the voltage across a linear circuit such as a resistor, the current will also double. However, if the resistance is doubled, the current will fall in half.

This can be expressed as an equation relating voltage, current and resistance and this is V = I times R, V=I.R. This is the standard Ohm's law formula and it is used in virtually every electronic circuit design t that the right current levels and voltage levels are present in circuits and electronic equipment. It is also used for electrical work as well where it is equally applicable. In fact, any situation where a potential difference or voltage and current need to be determined, Ohm's law is likely to be used.

It is possible to manipulate the basic Ohm's law equation of V=I R to also calculate the other variables: R = V / I and I = V / R.

In order to remember these, many people use an aid memoire called the Ohm's law triangle. This is a triangle where V is placed at the top and I and R at the bottom. It is possible to use this Ohm's law triangle as an easy method of remembering the basic equation.

It is possible to demonstrate Ohm's law using a simple resistor, a variable voltage and meters for current and voltage. Applying a voltage both current and voltage can be measured. This can be repeated for various input potential difference levels. If plotted it is found that the resulting plot of current vs voltage is a straight line. It is also possible to calculate the resistance of the resistor by dividing the potential difference by the current. At each point they should be the same within experimental limits.

Standard resistors, connecting wire and the like all give a straight line plot of current vs voltage, and as a result they are called Ohmic conductors. Other devices may not follow a straight line: incandescent or filament lamps and semiconductor diodes are two examples and they are called non-Ohmic conductors.

Ohm's law is one of the basic laws of electrical science and is widely used in all areas associated with electrical science including electronic circuit design.
