What is meant by negative half-cycle of an alternating current?
Alternating current varies in magnitude, and reverses direction every half-cycle. When the current is drifting in one direction we allocate it a 'positive' direction; when it reverses direction we allocate it a 'negative' direction. So the positive half-cycle refers to its variation in current during its forward or positive direction and the negative half-cycle refers to its variation in current during its reverse or negative direction.
What is full wave bridge rectifier?
A: This type of rectifier circuit will conduct current trough a load both times during the AC positive and negative cycle
Why does the output frequency of a full wave rectifier double that of input frequency?
One cycle of the AC input consists of a positive half-cycle followed be a negative half cycle. The FW rectifier basically reverses the polarity of one of the half-cycles, so there are now two positive pulses per single input cycle, effectively doubling the frequency. Of course the rectifier may be wired for the opposite polarity, with two negative pulses per input cycle, but the same principle applies.
Why full eave rectifier rectifies negative half cycle?
the rectifier is Mainly used to convert the Ac current into DC current .In rectifier there are two diodes or (4 Diode In full wave bridge rectifier )are use is to conduct the current one is connected in forward bias(i.eD1) and the other is connected in reveres bias(i.eD2). As we know that the diode is conduct the current throw it When it is connected in forward bias . now when the voltage is applied to the circuit the the AC Current is start to flow throw circuit and in Positive half cycle of Ac current the Diode is Allow the current Pass throw it and during the Negative half cycle the Diode D2 is allow the current pass throw it and in these way the rectifier rectifies positive As Well As the negative half cycle
What does the term cycle refer to in AC circuits?
The current or voltage have a frequency in an AC system. It is 50 or 60 hertz per second. It is also known as 50 or 60 cycles per second. Each cycle is set of positive and negative amplitude. Refer Sinusoidal wave for further details.

Positive and negative effects on clocks?
A positive impact of clocks is that they help people tell time. A negative impact of clocks is that they interfere with the sleep cycle.

Why capacitor does not store alternate current but store direct current?
Because Alternet current has both positive as well as negative cycle capacitor does not conduct for negative cycle of the Alternet current and DC all are positive cycle thats why it capacitor conduct for DC not for AC
How does a rectifier work?
In a simple half-wave rectifier, during the positive part of the alternating wave the diode conducts, making the load voltage equal to the supply voltage. During the negative part of the alternating wave he diode blocks, making the load voltage zero.Another explanationFor as long as its circuit is alive, any sine wave signal running at a certain frequency has the positive part of its wave immediately followed by the negative part of its wave immediately followed by another positive part of its wave, and so on.A half-wave rectifier would basically eliminate the negative part so the output of the rectifier, as seen by the load that is connected to it, would receive a positive half wave voltage then a zero voltage during the negative half cycle of the waveform, then a positive half cycle again, and so forth.A full wave rectifier does the same thing for the positive half of the cycle and then basically flips the negative part of the waveform to give the same output as the positive part, so you have a series of positive pulses. The signal, as seen by the load after the rectifier, never goes negative.
Can you conceive late in cycle and therefore get a negative pregnancy test result?
yes it happen to me according to doctor i just conceive before my due date so get 5 negative result i got my positive result after 15 days
Is a water cycle negative or positive?
one of the many effects is that it may cause floods
Find the output waveform of op amp when inverted input terminal connected to a ground and a sinusoidal signal of 4 v peak at non inverting input?
In this configuration the opamp basically works as a non inverting comparator. During the positive cycle of the waveform the output will saturate to positive Vcc, while during the negative cycle the output saturates to negative Vcc. Therefore the output waveform is a square wave with amplitude equal to the supplies and period equal to the input waveform.

What is The magnitude of an alternation which varies from zero is called its?
I will first answer this from an electrical viewpoint. The maximum positive excursion from zero would be the PEAK, or MAXIMUM portion of the cycle. From a magnetic point, it would be POSITIVE. The negative excursion of the electrical cycle (below zero) would be the MINIMUM. It would be NEGATIVE from a magnetic perspective.
