FACTS ABOUT CONDENSORS

(Continued from Page 12.) inductance of the aerial circuit is in- | creased, with a resultant increase in the wavelength of the aerial. If you lengthen the wires forming your aerial without increasing their number, you are increasing the total inductance of the aerial. It is obviously impracticable to be contiuually altering your aerial each time that you wish to increase or decrease the wavelength to which your aerial is to be tuned. To enable you to effect this altering of wavelength your inductance and condenser ate inserted into the circuit. To alter the tuning of the receiving instrument you vary the inductance and capacity of the circuit by varying the adjustment of your variable inductant, or variable condenser. In the same way you alter the position of the weight of a pendulum to regulate the rate at which the pendulum shall swing, and thus to control the clock. Thus you will see that inductance and capacity may be said to be the electrical counterparts of inertia and elasticity.
