what is the relationship between power and energy?
481540
Energy and power are closely related but are not the same physical quantity. Energy is the ability to cause change; power is the rate energy is moved, or used.

The relationship between Force and Energy is that: E = Force * Distance. If a force (weight, for example) of 1 Newton, is moved, against the direction of the force, by 1 Metre, the work done is i Joule. Additionally, if that 1 Joule of energy is to be expended in 1 second, the power required is 1 Watt.

Voltage is known as potential or in simpler terms “how fast the electrons flow”. Power is a function of voltage times the volume of electrons (current). Power is the ability to do work and is measured in Watts. The higher the voltage the more power you have with the same current (Watts (power) = Volts x Amps.

There is a significant difference between work and energy. Work is the transferring of an amount of energy with the help of a force covering a particular distance through a direction. Energy is also referred to the force which works in a certain distance. These both can be termed as scalar units.

Back to Berra's theorem, torque is the capacity to do work, while power is how quickly some strenuous task can be accomplished. In other words, power is the rate of completing work (or applying torque) in a given amount of time. Mathematically, horsepower equals torque multiplied by rpm.

Work is done when a force, F, moves through a distance. Power is defined as the rate of doing work. Just like speed determines how quickly we can travel a certain distance, power determines how quickly we can perform a certain amount of work.

The electrons originate in your body. Energy passes through your body, causing free electrons to vibrate in unison. What is the relationship among electric power, current, and voltage? Power is current times voltage.

There is a strong connection between work and energy, in a sense that when there is a net force doing work on an object, the object's kinetic energy will change by an amount equal to the work done: Note that the work in this equation is the work done by the net force, rather than the work done by an individual force.

Force vs. Power. ... Force is the fundamental result of an interaction between two objects, while power is an expression of energy consumed over time (work), of which force is an element. Force and power can both be described and measured, but a force is an actual physical phenomenon, and power in itself is not.

States the relationships between current (amps), resistance (ohms) and voltage. Watt's Law: States the relationships between power (watts), current (amps) and voltage.

Power (watts) is volts times amps. A few electrons under a lot of potential can supply a lot of power, or a lot of electrons at a low potential can supply the same power. Think of water in a hose. A gallon a minute (think amps) just dribbles out if it is under low pressure (think low voltage).

The current is equal to the electromotive force of the source divided by the total circuit resistance. Power. Power (P) is a measure of the rate at which energy is delivered or used by a circuit element. Voltage sources deliver power, while resistors use power (by dissipating it as heat).

Difference Between Work and Energy. There is a significant difference between work and energy. Work is the transferring of an amount of energy with the help of a force covering a particular distance through a direction. Energy is also referred to the force which works in a certain distance.

Electric power is the energy per unit time converted by an electric circuit into another form of energy. We already know that power through a circuit is equal to the voltage multiplied by the current in a circuit: P = V I .

['Power is defined as the rate of doing work, it is the work done in unit time, and the SI unit is given as watt (W) which is joules per second (J/s).', 'The formula is given by P = V x I.']

What is the difference between joule heat and power? When electric current flows in a circuit, energy is transferred from one point to another. The electric energy is not completely transferred but a portion of it is converted to heat energy. This is similar like friction force opposing some mechanical work.

Energy is the ability to do work. It powers every machine and is necessary for every activity.
