Difference between Ohms and Watts

There is a lot of confusion about the difference between ohms and watts. Many people think they are the same thing, but they are actually quite different. In this blog post, we will discuss the difference between ohms and watts and how they are used in electrical circuits. We will also provide some examples to help illustrate the difference between these two terms. So, without further ado, let’s get started!

What is Ohms?

Ohms is the SI unit of electrical resistance, named after Georg Ohm. Ohm’s law states that the current passing through a conductor is directly proportional to the voltage applied to it, and this equation is used to calculate the amount of current in a circuit. The Ohm’s law formula is I=V/R, where I is the current in amps, V is the voltage in volts, and R is the Resistance in ohms.

If the voltage and resistance are known, the Ohm’s law formula can be used to calculate the current passing through the circuit. However, if the current and voltage are known, the resistance can be calculated by rearranging the Ohm’s law formula to R=V/I. The Ohm’s law formula is a simple and essential tool for understanding electricity and designing circuits.

What is Watts?

Watts is a unit of measurement that describes the rate of energy transfer. It is named after James Watt, the inventor of the steam engine. Watts are often used to measure the power output of electrical devices such as light bulbs and motors. One watt is equal to one joule per second.

Watts can also be used to measure the rate of heat transfer. For example, a kilowatt-hour is a unit of energy that is equal to one thousand watts per hour. Watts are an important part of many aspects of our lives, from electricity to heating and cooling. Understanding watts can help us to save energy and money.

Difference between Ohms and Watts

  • Ohms and Watts are two important electrical units. Ohms measure the resistance to the flow of an electric current, while Watts measures the amount of power that an electric current can generate. In order to understand the difference between these two units, it is necessary to understand how they are used.
  • Ohms are typically used to measure the resistance of electrical components such as wires and resistors. On the other hand, Watts are used to measure the amount of power that an electric current can generate.
  • For example, a 100 watt light bulb will generate more power than a 60 watt light bulb. In general, Ohms are used to measure static properties while Watts are used to measure dynamic properties.


Watts and ohms are two of the most important concepts when it comes to understanding electricity. They’re also both pretty confusing, especially if you don’t have a scientific background. But don’t worry, we’re going to break it down for you. In this article, we explained the difference between watts and ohms and how they relate to each other. We also showed you how to calculate wattage and resistance using Ohm’s law.
