In an AC circuit including an inductor & a capacitor, the current and the phase of the voltage are usually different. If you change the circuit components or the power frequency, then the whole circuit will appear simply resistive. Once the LC circuit reaches this condition, then it is known as resonance. In this condition, the circuit reaches the whole impedance or high value. The main essence of resonance is that the energy of the magnetic field within the inductance & the energy of … [Read more...]

Some of the applications of oscillators are clock generators in calculators, computers, digital clocks, video games, etc... The signals generated by oscillators are also used in radio … [Read more...]
What is Colpitts Oscillator : Circuit & Its Working
A circuit that produces alternating and continuous waveforms is known as an oscillator. The waveform can be a sine wave, square wave, etc. based on their output frequency, oscillators are divided into various types. Electronic Oscillators' frequency can be controlled by their input voltage, so they are termed voltage-controlled oscillators. There are many types of oscillators but mainly divided into two categories. One is Harmonic Oscillators or Linear Oscillators and the second one is … [Read more...]
