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 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.
What is the equation for wattage?
Wattage = voltage times amperage. That's for DC. For AC there is a power factor PF = cos phi you have do multiply with.AnswerThe above answer suggests that power ('wattage') is an electrical unit, which it is not. In fact, power is defined as the rate of doing work, so the basic equation is work divided by time.
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.
How did scientists apply albert Einstein's quation E equals mc2?
Scientists applied Einstein's equation E=mc^2 in the field of nuclear physics to understand the equivalence between energy and mass. This equation helped in the development of nuclear power and nuclear weapons by showing the enormous amount of energy that could be released from a small amount of mass through nuclear reactions.
Mass physics equation?
mass=density*volume
How do you find power given force in physics?
Power can be calculated by multiplying the force applied to an object by the velocity at which the object moves. The formula for power is P = Fv, where P is power, F is force, and v is velocity. This equation shows the rate at which work is done on an object.
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)
What is the power unit for physics?
Watt
What is the energy of transition equation used for in the field of physics?
The energy of transition equation is used in physics to calculate the energy required for an electron to move from one energy level to another within an atom. This equation helps scientists understand the behavior of electrons and the emission or absorption of light in atomic systems.
