 PowerIs what We are looking for .. Is the heat .. Movement .. All the things that we aim torun .. Is Relationship between the power flow .. And the amount of this flow ofelectric charge .. As we have stated that Voltage can be represented by a strong water .. And the amount of waterflowing is the current Which depends on the size of the pipe resistance The more force Zadeh Flowing water .. And quantity in the pipes .. Whenever we get a result more .. Electric Power :Circuit voltage applied to the connector leads to the flow of electrons. Effort is Force and the flow of electrons is the movement. do the job rate of the socalled "energy"power and represent Symbol "P". measured in energy units "watt"watts and represents the symbol "W". known as the watt "The rate of work done in a circle at the current of 1 amp of effort due to the application of 1 volt.Laws (formats) the ability Energy consumed in the resistance depends on the amount of current that passes through the resistance at The application of a particular 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. Specifications Capacity (consumption rate) Equipment Power Rating Rate is estimated Istlak equipment in watts. This rate index on the rate at which the play equipment Electric convert electrical energy into other forms of energy such as heat or Light. the rate of consumption of the lamp house is common for voltage220 volts) 110 volts) is 100 watts. using Ohm's law can calculate the resistance of the lamp.
Using Ohm's law the basic Imkmen calculate the value of current flowing in the lamp his 120 volt And its 100 watt.
And if the rate of the lamp voltage 120 volts and capacity of 75 watts are 192 current resistance 0.625 amps through it 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 beharmed (damaged) items Electricity if the temperature is too high. That is why the classification ofequipment Electrical often on the basis of maximum consumption rate of the capacity of the socalled "power Power "wattage. the higher the rate the 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
