Just as potential energy is developed in a weight when it is lifted against the earth's attraction so electrical energy appears in the disc while it is being separated from the plate.
Now the number of joules of electrical energy in an electric circuit is expressed by the following formula: Joules = volts x amperes x seconds, or since 1 joule = 0.
Let us now consider a condition of operation when there is no current in the secondary coil and the primary coil is connected to some source of electrical energy.
It consists of a resistance, which can be easily varied in value, placed in the circuit connecting the motor with the source of electrical energy.
This circuit is composed of a source of electrical energy, such as a number of dry cells, a kick coil, the connecting leads, and a special operating switch for opening and closing the circuit to produce the spark.
Diagram illustrating the action of mutual induction between two circuits; the one including a source of electrical energy and a switch; the other including a galvanometer, but having no cell or other electrical source.
Although electricity is not energy, electricity under pressure is a form of energy spoken of as electrical energy.
With large powers, such as are here considered, a horse-power hour of electrical energy may be developed for materially less than 0.
The cost ofelectrical energy at the switchboard in a water-power station is subject to wide variations, owing to the different investments necessary in the hydraulic work per unit of power developed.
Second, if the daily flow of water is equal in capacity to the daily output of electrical energy, how far can the water-power be devoted to the development of that energy?
During this same period of five years the gross income from sales of electrical energy, developed in large part by water-power, increased forty-seven per cent.
About 4 per cent of this power is converted into heat in the process of transformation, making a loss in electrical energy of a little over 40 horse-power.
You will be able to see from the above illustration that heat, electrical energy, and mechanical energy are really the same.
But the little battery with its metal plates in a weak solution proved a perennial reservoir of electrical energy, safe and controllable, from which supplies could be drawn at will.
By connecting all these springs in circuit with a galvanometer and revolving the shaft rapidly, a notable deflection is obtained of the galvanometer needle, indicating the production of electrical energy.
Electrical energy can be transmitted to a distance, and even to many thousands of miles, but can it be transformed at the distant place into mechanical or any other required form of energy, nearly equal in amount to what was supplied?
Electrical energy is obtained in various ways, but the generators get heated; and one great object of inventors is to obtain from machines as much as possible electrical energy of the energy in the first place supplied to such machine.
In this analogue the fluid may be likened to electricity or electrical energy, the tank to the condenser, the spring to the dielectric, and the pipe to the conductor through which electricity is supplied to the condenser.
The largest expense in the process, apart from the cost of electrical energy, is the preparation of aluminium oxide free from other oxides, for most of the oxide found in nature is too impure to serve without refining.
Most of the electro-chemical industries of the country are carried on where water power is abundant, since this furnishes the cheapest means for the generation of electrical energy.
Some meters are subject to a multiplying constant so stated on their face and the registration of such meters must be multiplied by the constant as shown, to determine the actual consumption of electrical energy.
When a motor fails to start, it should first be ascertained if a supply of electrical energy be available in the mains.
A true transformation takes place, and the proportion which the rate of delivery of electrical energy bears to the power absorbed, or in other words the efficiency, is the more remarkable.
Little practical use could be made of electrical energy so long as its only known sources were frictional machines and voltaic batteries.
The term wattless current, as understood, does not indicate an absence of electrical energy in the circuit; its elements are there, but not in an available form for external work.
It simply needs more iron, more copper wire, and more rapid motion, to give us the 4800 watts of electrical energy we are seeking.
In each of the above three cases the amount of electrical energy is 55 watts.
A fair average of the retail values of fuels and of electrical energy and an average luminous efficiency of the light-sources involved have been used in making the computations.
In the vacuum lamp nearly all the electrical energy is converted into radiant energy, which is emitted by the filament and any dissipation of heat is an energy loss.
This increase of four times in the intensity of illumination involved an increase in consumption of electrical energy of three times the original amount at an increase in cost equal to 1.
The luminous output of such lamps is much greater than that of an ordinary carbon arc using the same amount of electrical energy.
The above list will hopefully provide you with a few useful examples demonstrating the appropriate usage of "electrical energy" in a variety of sentences. We hope that you will now be able to make sentences using this group of words.
