Current electricity is defined as the flow of electrons from one section of the circuit to another. Electromotive Force (EMF) and Voltage: When two bodies at different potentials are linked with a wire, free electrons stream from Point 1 to Point 2, until both the objects reach the same pot...
Electric Current Formula: The flow rate of electric charge is calculated by dividing the change in charge by the change in time. Electric Current Units: The SI unit for current is the ampere (A), representing 1 coulomb of charge passing a point in 1 second. AC vs DC Current: Alternating...

Where, Electric current is the rate of change of electric charge through a circuit. This electric current is related to the voltage and resistance of the circuit. Using Ohm’s law, we can represent as the formula: I=VR Where, Since we measure the charge in coulombs and time in seconds,...

Current Divider Formula vs. Voltage Divider Formula It is quite easy to confuse these two equations, getting the resistance ratios backward. One way to help remember the proper form is to keep in mind that both ratios in the voltage and current divider equations must be less than one. After...
However, PUE over the year (\({\mathrm{PUE}}_{\mathrm{CYP}})\) could be calculated by using the following formula: $${\mathrm{PUE}}_{\mathrm{CYP}}= \frac{\mathrm{CY}}{\mathrm{CYP}}$$ (3) where CYP = Crop year precipitation in mm. Soil water use efficiency (SWUE) ca...
