an Hartley oscillator uses a tapped inductor ( i.e an inductor with an additional connection at a suitable position in turns of the coil. ) with a specific tap ratio as per the circuit gain and design. For Low Frequency oscillators large inductances are required which have large number of coil turns. It is possible to get suitable ratios for such values hence this circuit is prefered.

What are the applications of hartley oscillator?
hartley oscillators are mainly used in radio receivers. Also note that due to its wide range of frequencies it is the most popular oscilator
What are the applications of RC phase shift oscillator?
RC phase shift oscillators are used for musical instruments, oscillators, voice synthesis, and GPS units. They work at all audio frequencies.
Why LC oscillators are not used for low frequency?
They are not suitable for use as extremely low-frequency oscillators because the inductors and capacitors would be large in size, heavy, and costly to manufacture.
Why 33pf capacitor is used in oscillator circuit of microcontroller?
Capacitors can be used for many purposes - for debounce of inputs, power isolation, curcuit loading. Some microcontrollers have D/A converters, oscillators, or transmitters built in and require external capacitors to operate these at specific frequencies.
What types of diodes are used in high frequencies?
Two types used at microwave frequencies are gunn and PIN diodes.

What are oscillators used for?
Signal generators: reference (tuning equipment) source - such as electronic keyboards beat frequencies - as in a superheterodyne radio
Why RC oscillators are not used for high frequencies?
The "C" in RC is capacitance, and at high frequencies, the C will shunt the signal more than at lower frequencies. The loss through the cap will climb right along with frequency. And as the cap's performance goes down, so, too, does the circuit performance. RC oscillator performance is far from linear at the top of the frequency range.
Why LC oscillator not suitable for audio frequency?
Another type of sine-wave generator uses inductors and capacitors for its frequency-determining network. This type is known as the LC OSCILLATOR. LC oscillators, which use tank circuits, are commonly used for the higher radio frequencies. They are not suitable for use as extremely low-frequency oscillators because the inductors and capacitors would be large in size, heavy, and costly to manufacture.
What substance in its crystalline form is used in oscillators?
Quartz crystals are used in piezoelectric mode as stable frequency references for oscillators. The quartz is shaped and polished to the size and thickness that produces the desired frequency when stimulated.
What is function of ic lm324 in any circuit?
An LM324 IC contains operational amplifiers. LM324 ICs can be used for different purposes in circuits, such as oscillators, rectifiers or oscillators as well.

Why crystal oscillator used for microcontrollers?
Oscillators are connected externally with the microcontroller to provide high frequency signal to the oscillator circuit in the microcontroller. The oscillator circuit provides the clock signal to the micro controller. Usually "PIEZO CRYSTAL OSCILLATORS" are used in micro controllers.
What is the function of crystal in IC?
Not sure what your question means. In an IC (Integrated Circuit) the circuit is etched onto a single crystal of Silicon. So the crystal forms the semiconductors within the IC. or Quartz Crystals are used in electronics as stable oscillators. They vibrate at precise frequencies, which can then be used for radio transmission or reception, or can form a time base for clocks or clock pulses, used for digital electronics.
What types of diodes are used in high frequencies?
Two types used at microwave frequencies are gunn and PIN diodes.
