The half-wave rectifier is conducting during only half of each cycle, so the
fundamental output frequency is 50 Hz, and there are loads of harmonics
of 50 Hz. also present in the output.
A: It can be positive or negative DC pulsating waveform
Output of the 50 Hz full-wave rectifier consists of 100 Hz positive pulses.
The total number of them is (100) times (number of seconds the rectifier has been operating).

The frequency on an amplifier response curve which is greater than the frequency for peak response and at which the output voltage is 1/√2 (that is, 0.707) of its midband or other reference value.
The bandwidth of a circuit, amplifier etc has been chosen to be defined by the points when the power output falls to half its maximum. Log 0.5 is -0.3 which in the decibel notation is -3dB (-0.3 Bels= -3 decibels). When the output power is at 0.5 maximum, then since the power varies as the square of the voltage, the output voltage is 0.707 of the maximum output voltage.
Flashlight by light, battery, circuit, a hood and a reflective cup, circuit storehouse, switch, etc, the basic principle is the current from the battery, and then to the circuit, after adjusting circuit voltage and current, and then output to the light source for lighting.
The DC voltage for the amplifier (transistor or FET) runs for a series-fed oscillator through the inductance of the LC circuit. A shunt-fed oscillator uses a radio-frequency choke or a resistor to deliver DC voltage to the amplifier. For an oscillator the difference between serial-fed and shunt-fed is small. The choke resonance frequency can interact with the LC circuit resonance frequency. This problem happens only with shunt-fed. Furthermore series-fed needs less components. Therefore it is prefered for (low power) oscillators. The output circuit of an amp can be series-fed or shunt-fed, too. The additional DC current through the coil will drive a iron or ferrite core earlier into saturation. This is an disadvantage of serial-fed. At a high-voltage tube RF amp with say 2000V DC voltage, in the shunt-fed amp only the choke and the DC blocking capacity have to withstand the high voltage. This is an advantage of the shunt-fed solution.
Independent SourcesIndependent sources produce current/voltage at a particular rate that is dependent only on time. These sources may output a constant current/voltage, or they may output current/voltage that varies with time.Dependent SourcesDependent sources are current or voltage sources whose output value is based on time or another value from the circuit. A dependent source may be based on the voltage over a resistor for example, or even the current flowing through a given wire. The following sources are possible:Current-controlled current sourceCurrent-controlled voltage sourceVoltage-controlled current sourceVoltage-controlled voltage sourceDependent sources are useful for modelling transistors or vacuum tubes.
The effect of an RL circuit in half wave rectifier is that the voltage output wave forms for current and voltage will be modified .
Output voltage is higher!!!
twice the input frequency
switching frequency is the one which regulates the switching device in a electronic circuit,by which the output voltage can be determined or can be cntrolled
ANSWER In rectifiers for power supplies, the capacitor size is determined by the allowable ripple on the output. This can be determined by the rate at which the capacitor is drained. Specifically, this rate is the current drawn from the capacitor. Assume a half wave rectifier made from four diodes. For part of the cycle, the output current is supplied by the rectifier diode. This is also when the capacitor is charged. While the rectifier is not supplying current -- when the input waveform has dropped below the output voltage -- the capacitor must supply the current. Then, as the input waveform rises above the capacitor voltage, the rectifier supplies the current to charge the capacitor and the output circuit.
Bridge Rectifier
A linear circuit is an electric circuit in which, for a sinusoidal input voltage of frequency f, any output of the circuit (current through any component, voltage across any component, etc.) is also sinusoidal with frequency f. Note that the output need not be in phase with the input.
A bridge rectifier circuit used to convert A.C to D.C. and can also be used as a polarity protection circuit. Because irrespective of which of the input terminals is given +ve voltage , the output voltage is +ve at only one output terminal. hence polarity protected.
An open diode will result in no output from a half wave rectifier, and an open diode will cut the output of a full wave rectifier in half.
low output
It should be the rms value of your supply.
Transfer Characteristic basically is relation between output and input of a electronic circuit. So in case of a series circuit in which a diode and a resistor are in series and the output voltage (Vo) is being measured accross resistor the relation between Input voltage (Vi) and Output voltage (Vo) will be Vo=Vi. When the we will represent it graphically we will get a straight line graph.
