these two parameters gives the power of the electricity (P) in watts, and multiplying P by the time during which the electricity flows (t) in seconds gives the amount of electrical energy in the system, in joules. The mathematical expression for electrical energy in a conducting circuit is ...

In the study of electricity, the power formula is: P=VI where V is the voltage in a circuit and I is the current flowing through that circuit. Knowing what the word "power" means to physicists helps you understand the units of power. In the SI (metric) system, the ...
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...
R is the symbol for resistance. It is the only formula in electronics that I use pretty much every time I design a circuit. You can switch it around and get R = V/I or I = V/R. As long as you have two of the variables, you can calculate the last. Instead of memorizing it, ...
Efficiency can be expressed as a ratio by using the following formula: Output ÷ Input. Output, or work output, is the total amount of useful work completed without accounting for any waste and spoilage. You can also express efficiency as a percentage by multiplying the ratio by 100. ...
