Ohm S Law Made Easy

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.

Ohm s law made easy. By knowing this simple law you understand the concept that is the basis for the analysis of any electrical circuit. Example where i is the current in amperes v is the potential difference in volts and r is a constant measured in ohms called the resistance. Just enter 2 known values and the calculator will solve for the others. An anology would be a huge water tank filled with thousands of gallons of water high on a hill.

V ir where v is the voltage across the conductor i is the current flowing through the conductor and r is the resistance provided by the conductor to the flow of. Ohm s law is made from 3 mathematical equations that shows the relationship between electric voltage current and resistance.

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.

In short if you know two of these three quantities you can calculate the third. Ohm s law may sound a bit confusing when written in words but it can be described by the simple formula. Ohm s law is incredibly useful because it lets you calculate an unknown voltage current or resistance. Ohm s law states that the voltage across a conductor is directly proportional to the current flowing through it provided all physical conditions and temperature remain constant.

Where i is the current through the conductor in units of amperes v is the voltage measured across the conductor in. Calculate power current voltage or resistance. 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.

Now you should understand the concepts of voltage current resistance and how the three are related. Simple funny explanation. Where i current in amps v voltage in volts and r resistance in ohms this same formula can be also be written in order to calculate for the voltage or the resistance.
