This tool is useful for calculating the voltage drop on copper wires. Select the current type, fill in the other fields and then click on "Calculate".
This tool is useful for calculating the resistance and total dissipable power of two or more resistors connected in parallel or series. Parallel connection is used to obtain non-standard ohm values or high powers, while series connection increases total resistance.
Add or remove resistors as needed
This tool is useful for calculating the equivalent nominal values of the sections of conductors expressed in American Wire Gauge [AWG], square millimeters [mm²], circular mils [CMA] and others. Just enter a measure or a known value and all equivalent values will be automatically calculated.
This tool is useful for calculating the intensity of the electric current that flows in a conductor is in direct proportion to the applied voltage, and in inverse proportion to the opposite resistance. The electrical voltage is the cause, the electric current is the effect, the electrical resistance is the condition.
With this application that uses Ohm's law you can obtain any result in intensity of current, power, resistance or voltage starting from two other known values.
