Printable Ohms Law Wheel Learn how to use ohm's law and joule's law to calculate voltage, current, resistance and power. the web page provides a printable ohms law wheel with 12 formulas and a calculator tool. 12 volts ÷ 3 ohms = 4 amps. it’s as simple as that. let’s tackle another example to find a circuit’s resistance using the given values: voltage = 120v. current = 17 amps. now plug the known values into our formula wheel and work the equation. 120 volts ÷ 17 amps = 7.05 ohms. i told you it was simple.
Printable Ohms Law Wheel Ohm’s law in the preceding example, we know the following values: i = amps = 10 r = ohms = 12Ω e = volts = 120 p = watts = 1200 we can now see how the twelve formulas in the ohm’s law chart can be applied. watts p 1200. Learn what the ohm's law and pir wheel is, how to use it to calculate electrical values, and download a free printable version. the wheel shows the formulas for voltage, current, resistance, and power based on ohm's law and joule's law. Ohm’s law basics: • voltage and current are directly proportional • when the voltage is increased the current increases proportionately. • when the voltage is decreased the current decreases proportionately. • i = intensity of current in amperes • e = electromotive force in volts • r = resistance in ohms • p = power in watts or. Download and print a pdf of the ohm's law wheel and power matrix from learn electrics. watch a video that explains how to use them and practice with examples and questions.
