    Resistance to Power Calculator: Find Power Dissipation in Ohms

    Created by Md jony islam

    power calculation with resistance

    Find the power lost in a resistor based on the resistance or voltage, or current. Applied inthe design of circuits, electronics, and power calculations. The Resistance to Power Calculator estimates the power that is dissipated by a resistor fixed via resistance, voltage, or current. It helps to prove Ohm's Law and design the circuits safely.

    What do you need to know to calculate Resistance to Power?

    The Resistance to Power Calculator is used to estimate the amount of power (in watts) that a resistor will dissipate when it is known that a particular voltage or current is going through it. It supports all three standard forms of the power formula of Ohm Law:

    Frequently Asked Questions - Resistance to power Conversion FAQs:

    How many ohms is 1000 watts?

    In order to calculate ohms using 1000 watts, you must know the voltage. use R = V² / P, therefore if it’s 120V, R=14.4 ohms, and if it’s 240V, R=57.6 ohms.

    How many watts is 20 ohms?

    Power is a function of voltage or current, so if you are given voltage, use the formula P = V² / R, for instance, at 120V and 20 ohms—720 watts. Or you know, currently, use P = I² × R.

    Is high resistance good or bad?

    It all depends on the purpose; high resistance is good for heating devices like toasters ( produce heat), but bad for power lines, where it leads to energy loss.

    What device measures resistance?

    Resistance measurements are done by a multimeter or an ohmmeter, only that a little current is directed, and it measures the amount that is resistance.

    What is a watt in electricity?

    A Joule is a unit of electrical power equivalent to one Joule per second, which defines the measure of energy by how much energy a device consumes or produces in one second.
