The Electrical Current calculator computes the current based on Ohm's Law using Power (P) and Potential (V).
INSTRUCTIONS: Choose units and enter the following:
Electrical Current: The calculator returns the electrical current in amperes (amps). However, this can be automatically converted to other electric current units via the pull-down menu.
The Ohm's Law calculator suite computes power (watts), potential (voltage), current (amps) and resistance (ohms) in relation to each other based on Ohm's Law. There is a fundamental relationship between electrical parameters: potential, current, resistance and power depicted in the graphical wheel (see wheel).
The Ohm's Law Calculator suite has automatic unit conversions for the input and output of the equations. The equations are as follows. Click on the formula for a pop-up calculator with the formula, or click on the description link for the page dedicated to that formula.
watts, milliwatts, kilowatts
ohms, milliohms, kiloohms
amps, milliamps, microamps, gilberts
