Hey, it's Paul from theengineeringmindset.com. In this article, we're going to explore Ohm's Law and learn how to use it. Ohm's Law is a fundamental
... [Show More] concept in electrical engineering, describing the relationship between voltage, current, and resistance.
What is Ohm's Law?
Ohm's Law states that the current through a conductor between two points is directly proportional to the voltage across the two points. In other words, the higher the voltage, the higher the current will be. Additionally, Ohm's Law states that the current through a conductor is inversely proportional to the resistance of the conductor. The higher the resistance, the lower the current will be.
How to Use Ohm's Law
Ohm's Law can be represented by a simple equation: V = IR. Here, V represents voltage, I represents current, and R represents resistance. This formula can be rearranged to solve for any of the three variables. For example, if you know the voltage and resistance of a circuit, you can use Ohm's Law to calculate the current flowing through it.
Example Problems
Here are two example problems to test your understanding of Ohm's Law:
What is the current flowing through a 10-ohm resistor if the voltage across it is 5 volts?
If the current flowing through a 2-ohm resistor is 3 amps, what is the voltage across it?
By using Ohm's Law, you should be able to solve both of these problems.
Ohm's Law
Ohm's Law, named after German physicist Georg Ohm, describes the relationship between current and resistance in an electrical circuit. The law states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points, and inversely proportional to the resistance between them. This can be mathematically represented as:
V = IR
V represents voltage
I represents current
R represents resistance
This formula can be rearranged to solve for any of the variables. For example:
I = V/R
R = V/I [Show Less]
