Power

Power

.. Is what we are looking for .. Is the heat .. Movement .. All the things that we aim to run .. Is the relationship between the power flow .. And the amount of this flow of electric charge .. As we have stated that the voltage can be represented by a strong water .. And the amount of water flowing is the current, which depends on the size of the pipe the more resistance Zadeh force water flowing .. And quantity in the pipes .. Whenever we get a result more .. Electric power Electric Power

-Circuit voltage applied to the connector leads to the flow of electrons. Effort is the force and the flow of electrons is the movement. rate to make the job so-called "energy"power and represents the symbol "P". measured in energy units "watt"watts represents the symbol "W". knows watt as a "rate of work done in a circle at a traffic stream of 1 amp Result of the enforcement effort of 1 volt.

Laws (formats) the ability

Energy consumed in the resistance depends on the amount of current that passes through the resistance at a particular application of effort. which is expressed Bhasal hit effort in the current. P = E x I or P = EI

It can also calculate the energy by replacing the (compensation) other components of Ohm's law.

P = I2R and P = E2 / R

In the following diagram can calculate the power using any version of the ability

Rate is estimated Istlak equipment in watts. This rate is an indication of the rate at which to play electric equipment converts electrical energy into other forms of energy such as heat or light. the rate of consumption of the lamp house is common for voltage 220 volts) 110 volts) is 100 watts. using Ohm's law can be calculated Resistance lamp .

Using Ohm's law the basic Imkmen calculate the value of current flowing in the lamp 120 volt effort and ability 100 watt watts. using Ohm's law can be calculated resistance Almbbaham Ohm's law can be calculated resistance lamp.

And if the rate of the lamp voltage 120 volts and capacity of 75 watts be resistance 192 current passing by 0.625 amps when connected to rated voltage (120 volts).

Can be observed that the 100 watt lamp converts energy more quickly from the lamp 75 watt. lamp 100 watt, and will give more light and heat .

Heat

Passage of current through the material resistance causes heat. could be harmed (damaged) electrical components if the temperature is too high. That is why the classification of electrical equipment in many cases on the basis of maximum consumption rate of capacity called the "electric power"wattage. the higher the rate Wattage wattage the higher the possibility of equipment can dispel (distracting) dissipate heat.

Ability P .. Measured in watt "Watt" proportion of the world Scottish James Watt James Watt

Version of sporting ability in dc

.Should be mentioned In the specification of any electronic device or electric watt value required to run it .. It also expresses the value of the electrical consumption of the device .. As Zadeh ability .. Whenever the cost of electricity consumed higher .
