What does the current equals in a bridge rectifier?
In a bridge rectifier, the current output is the same as the input AC current during the positive half-cycle of the AC waveform. However, during the negative half-cycle, the diodes in the bridge configuration allow current to flow in the same direction, effectively converting AC to DC. The output current can be influenced by the load connected to the rectifier and may vary based on the input voltage and the characteristics of the rectifier circuit.
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.
Why in 4 diode full wave rectification you use bridge?
bridge is use in 4 diode fullwave rectification to allow complete cycle so that there will an output DC for both the positive and ndgative half-cycle of the input AC.
What is the meaning of current lags voltage?
'Current lags voltage' means that in the AC cycle the voltage peaks and the current peaks a little time (a fraction of a cycle) later. This happens with electrical loads like motors. When the current lags, there is a small period in each half-cycle when the voltage has reversed and the current has not reversed yet. This causes power to flow back into the supply from the load. So there is a loss of average power fed to the load for a given voltage and current. In this situation the power is the voltage times the current times the power factor, and the power factor is the cosine of the angle by which the current lags the voltage (counting 360 degrees as a full cycle).
What happen during positive cycle and negative cycle?
as direction of current reverses it is shown in form of positive and negative cycles
What is class c tuned amplifier?
Class C tuned amplifier is a large signal tuned amplifier that amplifies high power signals of the radio frequency range. The amplifier is said to be Class C if the output cycle obtained is less than half a cycle of the full input cycle. This means the transistor remains active for less than half a cycle so that only that much part of the input waveform is reproduced at the output with amplification. For the remaining part, the transistor remains inactive.
How can a class A guitar amp be push pull?
Set the output tubes so that both of them conduct the whole cycle. Low plate voltage with high current.
What is self amplification?
Self amplifying, cycle of acceptance and acknowledgment in you. It's the chain reaction that will ultimately define our ability to overcome imagined differences and look at life in the grand scheme of things

What is a class c amplifier?
A class A amplifier is an amplifier where the bias current in all amplifier stages, including the power amplifier, always exceeds the maximum output current. This leads to a very high energy consumption (and cooling might become a problem), but eliminates crossover distortions. Typical commercial amplifiers are what is called class A/B amplifiers, meaning, they would use a pretty high bias current to eliminate crossover distortions, but the bias current would still be less than the maximum output current to reduce the energy waste and cooling problems associated with pure class A amplifiers.
How do you determine the size of acapacitor in a rectifier circuit?
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.
How a system output can be brought out of limit cycle?
a system output can be brought out of limit cycle by comparing the exact y(N) unquantised by y(n) quantised.
The computing cycle is input processing output and?
storage
How can robots move?
Typically a computer is used to control a set of stepper motors which allow precise movement in steps. Power is achieved by the use of amplification boards which take input from the computer and output power to the steppers. Sometimes a feedback sensor, such as a touch sensor is used to start stop or cycle motions.
The most important output of the accounting cycle is the financial statements?
true
What is one of the compounds that is a direct output of the Calvin cycle?
One of the compounds that is a direct output of the Calvin cycle is Glyceraldehyde 3-phosphate (G3P). It is a product of the synthesis of carbon dioxide.
Input process output and storage is considered to be the what?
Information processing cycle
