OHMS LAW / WATTS LAW CALCULATOR - COPYRIGHT CROWN®
Ohm's Law states the relationship between current, voltage and resistance. Watt's Law states the relationships of power to current, voltage and resistance. For example, a 100 watt light bulb operating on 120 volts AC will have 144 ohms of resistance and will draw 0.833 Amps. Enter any two known values and press "Calculate" to solve for the others. Fields should be reset to 0 before each new calculation. This tool is useful when designing audio systems with various line distances and values. This Javascript calculator requires Microsoft Internet Explorer v4.0+ or Mozilla Firefox v1+ browser.
