Never fails me Ohm's law is ohm's law. This just makes it so darn easy to calculate.
Great Easy to use. Just checked it with answers I knew & they were correct. Very pleased.
Good ohms calculator convert easly different value
good very useful easy to use the only one you will ever need
Only wish is that it would do equivalent scales like kA, Kohm, mA, micro. Otherwise great app a lifesaver
Easy to use Nice for figuring amps for my ecig coils
Version 2 has finally landed...
We've completely changed the styling and functionality of the calculator. It's now much easier to carry out the calculations using the drop-downs to select the units.
Enter the two known values and then select the units for those values, from µ to M. The results will automatically display the correct units too, making them easier to understand.
A new page has also been added to the guide, it reminds you how to add together series and parallel resistances.
Freeze & alter any one of Volts,Amps,Ohms,Watts for rapid 'what-if' calculation.
