Formula for Electric Power The work done to move an electric charge q, measured in coulombs (C), across a potential gap V, measured in volts (v) is equal to the electric energy qV in Jou
The theory that the apparatus of counting of electric power and energy is in force, is wrong. The right formula of the electric power, is that it is analog in the third power of the electric current.The velocity of the current charges that pass through the apparatus, is analog to the ...

current I ampere (amp) A resistance R ohm Ω power P watt W What is the formula for electrical current? When the current is constant: I = Δ Q / Δ t I is the current in amps (A) Δ Q is the electric charge in coulombs (C), that flows at time duration of Δ t in seconds...
Understanding the electric power formula will help teams increase efficiency and make better, more informed decisions about the use of electrical energy. The electrical power formula is: P = V x I In this equation, I is the electrical current, V is the voltage, and P is the total electrical...
This formula is to be used for calculating electric power when only current I and resistance R are known to us. (ii) Power P in terms of V and R. We know that: P = V × I ………. (1) Also, from Ohm’s law we have,VI= R or V...
