Power refers to energy transfer per unit time; the SI unit of power is the watt; 1 watt is 1 joule/second.
There are several equations that involve power; the most basic one, of course, is based on the definition of power:
power = energy / time
There are several other equations for power; for example, the following equations are commonly used, specifically in electrical circuits:
P = IV
P = I2R
P = V2/R
... where P = power, I = current, V = voltage, R = resistance.

What is the fomular for caculating power of an object?
The formula for calculating power is power = work/time, where power is measured in watts (W), work is measured in joules (J), and time is measured in seconds (s).
What is the unit of q in the given equation?
The unit of q in the given equation is not provided.
What is the light power equation and how is it used in physics?
The light power equation, also known as the radiant flux equation, is P E/t, where P represents power, E represents energy, and t represents time. This equation is used in physics to calculate the amount of energy transferred by light per unit of time. It helps in understanding the intensity of light and its impact on various phenomena, such as heating, illumination, and photochemical reactions.
Explain how power is related to work.?
Power is the rate at which work is done, or the amount of work done per unit of time. The relationship between power and work can be described by the equation: Power = Work / Time. This means that the more power applied, the faster work can be done.
What is the equation for intensity and how is it used to measure the strength of a phenomenon?
The equation for intensity is I P/A, where I is intensity, P is power, and A is area. Intensity is used to measure the strength of a phenomenon by calculating the amount of power per unit area, providing a quantitative measure of how concentrated or powerful the phenomenon is at a specific point.

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.
What is the equation 2 to the power of 4?
2 to the power of 4 is an expression, it is not an equation.
