Answer 2

Oscillator: Oscillator is a device which can produce high frequency oscillation.

(i) Labelled Circuit diagram : (ref. image)

(ii) Working: As the key K is pressed, the electrical oscillations begin in the L

circuit or tank circuit. Inductance L is properly coupled with L

, there an induced e.m.f. is produced in L and its direction and magnitude both are changing. Thus, a flucting collector current is produced due to the flucting base potential, which helps the electric oscillations in tank circuit and hence an oscillation of conduct amplitude is produced in L

circuit. The energy is fulfilled by the battery.
