Electrical Potential - Ohm's Law. Ohm's law can be expressed as: U = R I (1a). U = P / I (1b) ... Electric Current - Ohm's Law. I = U / R (2a). I = P / U (2b). I ...
Ohm's law states that the electric current through a conductor between two points is directly proportional to the voltage across the two points.
Electrical power, measured in watts, can be calculated using Ohm's law. The power formula is P = V * I. If given voltage and current, this is easy to calculate ...
I = P / U = CALC. I = √ ( P / R ) = CALC.
The power of direct current (P) is equal to the product of the current (I) by the voltage (U), i.e.. P = I × U, where, P is the electrical power measured in ...
Power in general is the product of force and velocity. In a circuit, it's the product of voltage and current (P = VI). The watt is still the unit of power.
