Explain Ohm S Law In Simple Terms

Ohm s law current through and voltage across a conductor was first discovered by a german scientist george simon ohm.

Explain ohm s law in simple terms. And a series connected resistor in the circuit which resistance is 10 ω then what would be the current in that circuit. Or another funny way to explain ohm s law. Where i is the current through the conductor in units of amperes v is the voltage measured across the conductor in. It represents that the current is proportional to the voltage across two points with the constant of proportionality being the resistance.

Ohm s law is incredibly useful because it lets you calculate an unknown voltage current or resistance. A good way to understand ohms laws is an analogy with a domestic water system.

Go back if you dare to your high school algebra class and remember that you can rearrange the terms in a simple formula such as ohm s law to create other equivalent formulas. Ohm s law simple example. An ohmmeter is used for measuring resistance. By knowing this simple law you understand the concept that is the basis for the analysis of any electrical circuit.

Ohm s law states that the voltage or potential difference between two points is directly proportional to the current or electricity passing through the resistance and directly proportional to the resistance of the circuit the formula for ohm s law is v ir this relationship between current voltage and relationship was discovered by german scientist georg simon ohm. In short if you know two of these three quantities you can calculate the third. Now you should understand the concepts of voltage current resistance and how the three are related. The majority of equations and laws for analyzing circuits can be derived directly from ohm s law.

A multimeter can measure several functions including voltage current resistance and temperature. The concept behind ohm s law was first explained by german physicist georg ohm who the law is also named after. This law defines the relationships between current voltage and resistance. Ohm s law says that in an electrical circuit the current passing through a resistor between two points is related to the voltage difference between the two points and are related to the electrical resistance between the two points.

Introducing the constant of proportionality the resistance one arrives at the usual mathematical equation that describes this relationship. Ohm s law states that the current through a conductor between two points is directly proportional to the voltage across the two points. The same way that an electric current flows through a copper wire water flows through a copper pipe in a water system.
