##### How does the Direct Current (Electrical Engineering) Ohms Law Calculator work?
Free Direct Current (Electrical Engineering) Ohms Law Calculator - Enter two of the following items from the DIRECT CURRENT(DC) electrical engineering set of variables, and this will solve for the remaining two:
* I = current(amps.)
* V = Electricity potential of voltage(volts)
* R = resistance(ohms)
* P = power(watts)
This calculator has 4 inputs.

### What 1 formula is used for the Direct Current (Electrical Engineering) Ohms Law Calculator?

P = V x I
R = V/I
P = I2R
I = V/R
V = P/I
V = I x R

##### What 7 concepts are covered in the Direct Current (Electrical Engineering) Ohms Law Calculator?
current
the rate of flow of electricity. The unit of current is the ampere (A) which is defined as 1 ampere = 1 coulomb per second.
electric
the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge.
law
a mathematical statement which always holds true
ohms law
the current through a conductor between two points is directly proportional to the voltage across the two points
V = IR
power
how many times to use the number in a multiplication
resistance
the property of any object or substance of resisting or opposing the flow of an electrical current.
R = V/I
volt
the potential difference across a conductor when a current of one ampere dissipates one watt of power.
