Describe the construction of electric oscillators


In the circuit capacitor of capacitance C and a coil of inductance L are connected in series with a sphere gap G. The sphere gap has a high resistance until a spark jumps across but low resistance after the spark jumps. If the voltage across G is gradually increased, the charger on the capacitor will increase. When the voltage across G becomes high enough, a spark will jump and the capacitor wills then discharge. The current does not ceases at zero when the capacitor is completely discharged but continues, charging the capacitor in the opposite direction. It then discharged again, the current reversing in the circuit. The current oscillates until all the energy stored in the capacitor has been converted into heat by the resistance is high all the energy is used in the first surge and hence there are no oscillations.
