"Sixteen amperes," he remarked to himself, "I don't attempt to use the batteries when they fall below five. These are all right." From a case he took a little round black disc, about the same size as the other two. In its face it had a dozen or so small holes perforated and arranged in the shape of a six-pointed star.
"According to your magnetic drag meter, the conductors were carrying over fifty billion amperes. The small coils worked perfectly. They're charged again; the power went back into them from the big coil with only a five percent loss of power about twenty thousand megawatts." "Hey, Arcot," Wade said. "I thought you said we wouldn't be able to see the stars." Arcot spread his hands.
By not so much as by a vibration of the voltmeter needle, did the apparatus betray any strain as the load mounted swiftly. 100 200 500 1000 amperes. Still, that needle held steady. Finally, with a drain of ten thousand amperes, all the equipment available could handle, the needle was steady as a rock, though the tremendous load of 800,000,000 watts was cut in and out.
Usually, however, it is the weight of silver or copper deposited from their salts in a certain time which gives the current in amperes. Electro-plating is the principal application of this chemical process. In 1805 Brugnatelli took a silver medal and coated it with gold by making it the cathode in a solution of a salt of gold, and using a plate of gold for the anode.
For 3 hours this load was practically constant, when it was thrown off entirely. This gave on the night service but 30 per cent. of the contract hours. This motor required 5 amperes to drive the shafting, and but 8 amperes or one H. P. to drive the three job presses with the cylinder press off.
In order to have a constant power of one horse for 71/2 hours, at the rate of 40 amperes discharge, we must have more than nine cells per electrical horsepower; and 47 such cells will supply five electrical horse power for the time stated, and these 47 cells will weigh 2,633 lb.
Here they heard the soft purring of a large oscillator tube and the indistinguishable murmur of smoothly running AC generators powered by large contraterrene reactors. The elder Dr. Arcot glanced in surprise at the heavy-duty ammeter in a control panel. "Half a billion amperes! Good Lord! Where is all that power going?" He looked at his son. "Into the storage coils.
That is why trolley car companies, no matter how many passengers their cars carry, are so often on the verge of financial disaster. The margin of profit is too narrow. "But if you can get a locomotive built that will drag a hundred cars! Ah! how does that sound?" demanded Tom. "See the difference?" "Bless my volts and amperes!" exclaimed Mr. Damon. "I should say I do!
That is, by dividing the resistance of the circuit in ohms, by the electromotive force of the current you will get the amperes flowing in the circuit. Finally if you know what the resistance of the circuit is in ohms and the current is in amperes then you can find what the electromotive force is in volts since: Ohms x Amperes = Volts, or R x I = E
A movable contact arm that slides over and presses on the turns of wire is fixed to the knob on top of the rheostat. A rheostat that has a resistance of 6 ohms and a current carrying capacity of 1.5 amperes which can be mounted on a panel board is the right kind to use. Assembling the Parts.
