Page 51 - the circuit, and the entire operation is again repeated. These actions take place in rapid succession, a large number of times a second, constantly producing a change in the number of lines of force passing through the core, and thereby inducing a current in the secondary coil. A switch
Page 4 - The unit of energy is also the erg; for the energy of a body is measured by the work it can do. The unit of energy, the erg, is therefore also 1 dyne-centimeter. 17. The unit of power has no particular name in the
Page 5 - is desired to connect 32 cells, each having an EMF of 2 volts and an internal resistance of 4 ohms, in a seriesparallel group that will give the maximum current through an external resistance of 8 ohms.
Page 38 - Ohm's Law. The strength of a continuous current of electricity in a circuit is directly proportional to the electromotive force, and inversely proportional to the resistance of
Page 44 - equivalent of any element or group of elements. This conforms to the law that the amount (weight) of any element that will be liberated by a given quantity of electricity is proportional to the chemical equivalent of that element.
Page 29 - as many lines of force are left behind as are gained in advancing, and there is, consequently, no change in the number of lines of force passing through the coil; hence there will be no current generated in it.
Page 19 - arrowheads and compass needles in Fig. 14, where the current is assumed to be flowing downwards, or away from the observer. If the direction of the current is reversed, the direction of the lines of force around the conductor will also be reversed. ACTION OF ONE
Page 4 - has been proved that a maximum current is obtained from a given number of cells through a given external resistance, when the grouping of the cells is such that the internal resistance of the battery is, as nearly as possible, equal to the external resistance. That is, arrange the cells so that is, as nearly as
