Help I cant understand Oscillator circuit(transistor). Why does th magnitude of current goes on increasing? What is the role of LC circuit(as in hc verma)?

Hello Student,

In oscillator circuit the energy is transferred between inductor and capacitor.If there is no resistance in the circuit the oscillator will always keep working or else it will discharge through the resistance.
LC is omega of oscillation.
