Answer:
ohm law we have to explain or definition
Ohm's Law is one of the most fundamental of laws for electrical theory. The Ohms Law formula or equation links voltage and current to the properties of the conductor, i.e. its resistance in a circuit.
Explanation:
⬇️⬇️⬇️⬇️⬇️⬇️
Ohm's Law is one of the most fundamental and important laws governing electrical and electronic circuits. It relates relates current, voltage and resistance for a linear device, such that if two are know, the third can be calculated.
With current, voltage and resistance being three of the major circuit quantities, this means that Ohm's Law is also immensely important. Ohm's Law is used within all branches of electrical and electronic science.
It is used for calculating the value of resistors required in circuits, and it can also be used for determining the current flowing in a circuit where the voltage can be measured easily across a known resistor, but more than this, Ohm's Law is used in a vast number of calculations in all forms of electrical and electronic circuit- in fact anywhere that current flows.
Ohm's Law discovery
There is a mathematical relationship which links current, voltage and resistance. A German scientist named Georg Ohm performed many experiments in an effort to show a link between the three. In the days when he was performing his experiments there ⬇️⬇️⬇️were no meters as we know them today. Only after considerable effort and at the second attempt did he manage to devise what we know today as Ohm's Law.
What exactly is Ohm's Law? ⬇️⬇️⬇️⬇️⬇️
Ohm's Law describes the way current flows through a material when different levels of voltage are applied. Some materials like electrical wires present little resistance to the current flow and this type of material is called a conductor. Hence if this conductor is placed directly across battery for example, a lot of current would flow. In other instances another material may impede the flow of current, but still allow some though. In electrical circuits, these components are often called resistors. Yet other materials let virtually no current though and these materials are called insulators.
