Oke, here's an article about ohms and watts:

Understanding Ohms, Watts, and Their Relationship

In the world of electronics, ohms (Ω) and watts (W) are two fundamental units of measurement that are closely intertwined.

  • Ohms represent resistance, a measure of how much a material opposes the flow of electric current. A higher resistance means that less current will flow through the material for a given voltage.
  • Watts represent power, which is the rate at which energy is transferred or used. In electrical circuits, power is calculated by multiplying voltage (V) by current (I): P = V * I.

The relationship between ohms and watts is determined by Ohm's Law, a fundamental principle in electrical circuits. Ohm's Law states that the current (I) flowing through a conductor is directly proportional to the voltage (V) applied across its ends and inversely proportional to the resistance (R). Mathematically, this is expressed as:

I = V / R

Calculating Watts with Ohms and Voltage:

To calculate the power (watts) in a circuit with a given resistance (ohms) and voltage, we can combine Ohm's Law with the power formula:

P = V * I = V * (V / R) = V²/R


Let's say we have a circuit with a resistance of 0.23 ohms and a voltage of 12 volts. To calculate the power dissipated in this circuit, we can use the formula:

P = V²/R = (12 volts)² / 0.23 ohms = 626.09 watts

Important Note: This calculation assumes that the entire circuit is purely resistive. In reality, circuits often contain reactive components (like capacitors and inductors) that affect power calculations.


Ohms and watts are essential units in electrical circuits, and their relationship is governed by Ohm's Law. Understanding this relationship is crucial for designing, analyzing, and troubleshooting electrical systems. The power dissipated in a circuit can be calculated using the formula P = V²/R, where V is the voltage and R is the resistance.
