Calculate Heater Resistance



Formula

The formula to calculate the resistance of a heater is:

\[ R = \frac{V^2}{P} \]

What is Heater Resistance?

Heater resistance is the opposition that a heater element presents to the flow of electric current. It is a crucial parameter that determines the amount of heat generated by the heater when a specific voltage is applied. The resistance is measured in Ohms and can be calculated using Ohm’s Law, which relates the voltage, current, and resistance in an electrical circuit.

Example Calculation

Let's assume the following values:

Using the formula:

\[ R = \frac{120^2}{1500} = 9.60 \, \text{Ohms} \]

The heater resistance (R) is 9.60 Ohms.
