To calculate the Electrical Resistance (R):
\[ R = \frac{V^2}{P} \]
Where:
Watts and Ohms are units of measurement used in electrical systems. Watts measure the rate of energy conversion or transfer and is often used to quantify the output power of a system. Ohms, on the other hand, measure electrical resistance, indicating how much a device or material resists the flow of electric current. The relationship between these two units is defined by Ohm’s Law and the Power Law in electrical engineering, which states that power (in watts) equals voltage squared divided by resistance (in ohms). Therefore, “Watts to Ohms” typically refers to the process of calculating electrical resistance given power and voltage.
Let's assume the following values:
Using the formula:
\[ R = \frac{120^2}{60} = 240 \text{ Ohms} \]
The Electrical Resistance is 240 Ohms.
Let's assume the following values:
Using the formula:
\[ R = \frac{220^2}{100} = 484 \text{ Ohms} \]
The Electrical Resistance is 484 Ohms.
