Power, Voltage and Current are always inter-dependant to each other. This page shows you the DC power formula to calculate the power in a given circuit using the values of voltage and ampere. Power is the product of voltage and the current. It is given as P=VI, where P=Power, V=Voltage, I=Current. This page helps you to learn the DC current formula in a more effective manner. You could use this DC voltage formula to solve your circuits in your projects, colleges, etc.
This DC power formula will be a very useful formula for the candidates who are preparing for the competitive exams. DC current formula is one of the important formulae to be remembered by the high-grade school students.
