What is the frequency range of radio waves that can penetrate human body?
The frequency range that the radio waves can penetrate the human body is between 1Hz and 10 KHz. This frequency of the radio waves is however not dangerous.
What is RF coil?
RF (Radio Frequency Coil) is a coil, which is designed to resonate at a frequency some where in the radio spectrum frequency. See L C Circuit Link Below.
When you tune a radio to a certain station you match the frequency of the internal electrical circuit to the frequency of that radio station In doing so you employing the principle of?
Resonance
What is a tank circuit used for?
A tank circuit is used on a radio transmitter. It is an electronic circuit that is used to tune a specific frequency. The tank is made up of two components, an inductor and a capacitor. The two components are connected in a parallel with each other. This is where the term "tank" comes from. Used in a radio transmitter, it is tuned for maximum RF (radio frequency) output on the frequency the transmitter is tuned to.
What is use of RFC in Hartley oscillator?
it is a radio frequency choke which connects the dc supply to the circuit but isolate the dc supply from the high frequency oscillations generated in the feedback circuit
What is a local oscillation?
A local oscillator is used in a superheterodyne radio circuit for example.The incoming radio frequency is mixed with an internal local oscillator circuit to generate a new intermediate frequency (IF) .The local oscillator usually runs at a frequency of 470kHz and is generated by an inductor and capacitor(LC oscillator)

How the reception of a particular radio set station is selected on your radio set?
A particular radio station is selected on our radio set by adjusting the natural frequency of LC-circuitequal to the frequency of particular transmitting station.
What is the purpose of resonance circuit?
Resonance describes a 'condition' rather than a 'purpose', but it is made use of in (for example) radio circuits, in order to tune the radio to a particular frequency (the resonant frequency of the signal).
Which human sense is extended by a radio telescope?
The sense of vision is extended, because although the human eye does not see in the radio frequency range, telescopes can.
When you turn the knob of your radio to tune to a station what do you chang?
You change a variable resistor in the the tuning circuit. The value of the resistor dictates the frequency that the radio is receiving.
What are the differences between analog and RF circuits?
analog circuit is circuit that generates audio, sound, radio etc (waves of the natural world) RF stand for radio frequency, it is often refer to the property of signal transmission in high frequency (HF). If you say a circuit is RF, the circuit would be in the frequency range between 3kHz to 300GHz. The reason that RF circuit is special is because the performance of signals of higher frequency is different to other lower frequency AC circuits. When designing a RF circuit, RF engineers have to consider the type of wires, lengths, use of components, signal loss etc. It is because high frequency signals would take a piece of wire (longer than 1/10 of signal wavelength) as wires with many inductors and capacitors.
