There are several equations that involve power. The basic definition of power is energy divide by time, so that is one equation. In electricity, if you have a DC current, power = current x voltage. In the case of AC, power = current x voltage x power factor (in many cases, the power factor is close to 1).

What is the difference between power functions and exponential functions?
A power function has the equation f(x)=x^a while an exponential function has the equation f(x)=a^x. In a power function, x is brought to the power of the variable. In an exponential function, the variable is brought to the power x.
What is an equation that involves a number raised to a variable power?
An exponential equation.
What is the Solution of logarithmic equation?
The answer to the question depends on the nature of the equation. Generally speaking it will involve exponentiation (raising the log base to a power).
How do you know if a equation is a quadratic one?
You know an equation is quadratic by looking at the degree of the highest power in the equation. If it is 2, then it is quadratic. so any equation or polynomial of the form: ax2 +bx+c=0 where a is NOT 0 and a, b and c are known as the quadratic coefficients is a quadratic equation.
How do you describe a formula?
a mathematical relationship or rule expressed in symbols.
How does power relate to work in physics?
Work gives us energy in Joules, which can be subbed back into the first equation to solve for power.
Mass physics equation?
mass=density*volume
What does physics have to do with sonography?
Sound waves are governed by the wave equation... which is physics. Most things in life come down to physics when you look at them... apart from religion.
What is the second equation of motion in physics?
ut+1/2at2
What is a physical equation?
one involved in explaining the laws of physics
What is the chemical equation for power?
Power hasn't a chemical equation.
Are there any applications of poisson's equation?
Poisson's equation is a partial differential equation of elliptic type. it is used in electrostatics, mechanical engineering and theoretical physics.
What equation do you use to find the remaining side of a triangle with physics?
Magic
What is the term of mathematical equation based on the rules of physics?
The equations of motions.
What is the equation 2 to the power of 4?
2 to the power of 4 is an expression, it is not an equation.
What is the equation for height in physics?
Height of an object = (elevation of its top) - (elevation of its bottom)
How is Albert Einstein's equation Emc2 important today?
The equation, E = mc2, is important today because it is the basic equation of nuclear physics. So for example it is used to calculate the amount of energy produced by the fuel in a nuclear power station, or the amount of energy potentially released in a hydrogen bomb. It is also important is astrophysical models of stars, where energy is provided by nuclear fusion. The equation is used alot in particle physics to calculate the masses of particles produced and to calculate the the energy needed to produce particular particles.
