Quick Answer: What Is Power Example?

What is average power formula?

If the resistance is much larger than the reactance of the capacitor or inductor, the average power is a dc circuit equation of P=V2/R, where V replaces the rms voltage.

An ac voltmeter attached across the terminals of a 45-Hz ac generator reads 7.07 V..

Is power good or evil?

Power isn’t inherently evil, and it isn’t inherently bad to seek power. Without power, you can’t accomplish anything, good or evil. Even those who want nothing more than to make the world a better place, can’t do so without exerting the influence of personal power.

We have also seen that power is the ability of an individual or groups to influence another individuals or group. In this way influence is a relationship. It is a relationship between individuals or groups which can make another to act in a way that he may not do otherwise.

How do you find power?

Power is a measure of the amount of work that can be done in a given amount of time. Power equals work (J) divided by time (s). The SI unit for power is the watt (W), which equals 1 joule of work per second (J/s). Power may be measured in a unit called the horsepower.

What is the 5 rule in physics?

The purpose of the 5% Rule is to give you the option of eliminating a vertical axis intercept. When you have a vertical axis intercept that you believe exists only because of error in your data, the 5% Rule can be invoked (if all conditions are met) and the intercept may be dropped from you mathematical equation.

How do you calculate total power?

Power can also be calculated using either P = IV or P=V2R P = V 2 R , where V is the voltage drop across the resistor (not the full voltage of the source). The same values will be obtained.

What are five sources of power?
