Amazing Power Equation Physics

The equation used to calculate the power is.

Power equation physics. Power in science and engineering time rate of doing work or delivering energy expressible as the amount of work done W or energy transferred divided by the time interval t or W t. The Power Formula is used to compute the Power Resistance Voltage or current in an electrical circuit. In physics power is used to describe the rate at which energy is used.

Where V is the potential difference I is the electric current R is the resistance and P is the electric power Stay tuned with BYJUS for more such interesting articles. In physics power is the amount of energy transferred or converted per unit time. The standard metric unit of power is the Watt.

Moreover it is a very important thing that allows us to see the rate at which electrical energy transfers from an electric circuit. 7457 watts 1 horsepower. The equations for the energy of the wave and the time-averaged power were derived for a sinusoidal wave on a string.

T is time However the above is used mostly for mechanical power. 1 hp 7458 watts. So the more powerful a device is the more energy it will transfer each second.

This formula states that the consumption of energy per unit of time is called power. Where s is the distance traveled. The equation that describes power is.

In general the energy of a mechanical wave and the power are proportional to the amplitude squared and to the angular frequency squared and therefore the frequency squared. Power formula can be rewritten using Ohms law as P I2R or P V2R. In physics you can calculate power based on force and speed.
