When the voltage at which it is desired to operate the spark gap isso high that it will break down the particular insulation used in thecondensers or cause brush discharge, the connection of four con-densers, each of capacity C, as shown in Fig. 206, p. 380, will give aresultant capacity C, while subjecting each condenser to only half thefull voltage. 386 TRANSMITTING APPARATUS. Inductance Coils.—The principal inductance coils in a radio set arethe primary and secondary of the oscillation transformer and the an-tenna loading coil, and the three corresponding coils of the receivingset. The three coils, oscillation primary and secondary and loadingcoil, are very similar. In actual practice few operators
