CONDENSER, AERIAL SERIES.--A condenser placed in the aerial wire system to cut down the wave length.
CONDENSER, VERNIER.--A small variable condenser used for receiving continuous waves where very sharp tuning is desired.
CONDENSER.--All conducting objects with their insulation form capacities, but a condenser is understood to mean two sheets or plates of metal placed closely together but separated by some insulating material.
- Adjustable Condenser.--Where two or more condensers can be coupled together by means of plugs, switches or other devices.
- Aerial Condenser.--A condenser connected in the aerial.
- Air Condenser.--Where air only separates the sheets of metal.
- By-Pass Condenser.--A condenser connected in the transmitting currents so that the high frequency currents cannot flow back through the power circuit.
- Filter Condenser.--A condenser of large capacitance used in combination with a filter reactor for smoothing out the pulsating direct currents as they come from the rectifier.
- Fixed Condenser.--Where the plates are fixed relatively to one another.
- Grid Condenser.--A condenser connected in series with the grid lead.
- Leyden Jar Condenser.--Where glass jars are used.
- Mica Condenser.--Where mica is used.
- Oil Condenser.--Where the plates are immersed in oil.
- Paper Condenser.--Where paper is used as the insulating material.
- Protective.--A condenser of large capacity connected across the low voltage supply circuit of a transmitter to form a by-path of kick-back oscillations.
- Variable Condenser.--Where alternate plates can be moved and so made to interleave more or less with a set of fixed plates.
- Vernier.--A small condenser with a vernier on it so that it can be very accurately varied. It is connected in parallel with the variable condenser used in the primary circuit and is used for the reception of continuous waves where sharp tuning is essential.
CONDENSITE.--A manufactured insulating compound.
CONDUCTIVITY.--The conductance of a given length of wire of uniform cross section. The reciprocal of resistivity.
CONTACT DETECTORS.--See Detectors, Contact.
CONTINENTAL CODE.--See Code, Continental.
COULOMB.--The quantity of electricity transferred by a current of 1 ampere in 1 second.
CONVECTIVE DISCHARGE.--See Discharge.
