Significance of the ripple voltage on a rectifier circuit?
A: It really depends on the load requirement . Example driving a relay hi ripple with no capacitor is an advantage in efficiency for a sensitive amplifier it will cause mayhem with the performance
What would cause a meter to read negative voltage across a DC motor?
A DC motor generates power when it is rotating even when no supply is connected.
What is a Filko voltage regulator type VRD-444HD for?
A voltage regulator is just as it says. It regulates the voltage that the alternator in your vehicle puts out. Too much voltage and you'll overamp your wiring, and too little can cause parts not to function properly.
What cause panics in the 1800s?
The supply of goods exceeded the demand
What causes voltage on 1999 Saturn sl2 to go from 12.2V to 14V at random times?
The cause is the voltage regulator within the alternator (working normal). When the voltage higher it is charging the battery like after you start your car or have the headlights and wipers on. The voltage regulator keeps your battery charged up. In order to charge the battery, voltage must be higher than battery voltage.
What happens to the DC load voltage when the filter capacitor is changed?
When the filter capacitor in a DC power supply is changed, the load voltage can be affected based on the capacitor's value. Increasing the capacitance generally results in a smoother DC output voltage with reduced ripple, leading to a more stable load voltage. Conversely, decreasing the capacitance can increase voltage ripple and cause fluctuations in the load voltage, potentially affecting the performance of connected devices. It's essential to choose the appropriate capacitor size based on the specific load requirements and ripple tolerance.

What is meant by lead and lag?
The terms, 'lagging' and 'leading', describe the relationship between a circuit's load current and supply voltage. They describe whether the load current waveform is leading or lagging the supply voltage -always the current, never the voltage. Inductive loads always cause the current to lag the supply voltage, whereas capacitive loads always cause the current to lead the supply voltage.

What happen if the value of the dc supply is changed in amplitude modulation?
The rf output voltage should be proportional to the signal voltage in AM. A change in the DC supply voltage should also cause a proportional change to the rf output voltage.
What is the max dc voltagee to be obtained from a transformer with an 18 v rms secondary using a bridge rectifier ckt with a filter?
About 24 volts. Take 18 and divide by 0.707, then subtract about 1.4 to compensate for the two diodes that will always be in series with the load. Of course, any load will cause ripple, so the 24 volts is with nearly no load.
What is the overheating voltage of an electric motor?
Motors overheat due to excessive current, not necessarily voltage. Normal voltage can cause a motor to overheat if it is stuck (not spinning). The problem is not usually the voltage, but whatever is causing excessive current flow (usually because the motor is not spinning like it is supposed to).
How capacitor and resitor in a circuit effect the phase of input voltage?
A capacitor and a resistor has no effect on the supply voltage; however, this particular load combination will cause the load current to lead the supply voltage by some angle termed the 'phase angle'.
Can a short circuit cause low voltage?
Most likely a short circuit will cause no voltage. Due to the high current on a short circuit fault the over current protection of the circuit will trip. This will cut the voltage supply off completely.
What is the cause of excessive blow by?

When is a power supply regulated?
Mostly when we use electronic equipment that operate with digital circuits, signals, audio and in fact most consumer electronic devices require a smooth and stable source of supply to eliminate electronic noise and to ensure precision for voltage levels. The traditional power supply would use a transformer to step-down the AC voltage, then convert it to a DC by using a rectifier circuit. The DC which consist out of the ripple of the original AC which will required to be smoothed with a ripple filter capacitor. This will smooth the DC to look almost like the output voltage of a battery. By this stage the voltage is usable for many robust applications. However for most consumer electronics the filtering of the capacitor is not good enough to ensure a stable and smooth DC. Most modern microchips have very exact specifications which a power supply must comply too. Any ripple or fluctuation outside these limits will cause failure of the device or cause unwanted noise. Therefore a circuit as simple as a resister and a zener diode can be used to regulate the voltage. This will mean that the voltage from the ripple filter stage will be reduced to a voltage lower than the lowest meaningful instantaneous voltage of the filtered voltage. Then all the voltage lower or equal to the regulated voltage will be passed while everything higher will be absorbed in some form of resistance for linear devices. This regulator function would in most practical applications be in the form of an IC and often a heat sink is connected to it to deal with the dissipated power. This IC can also come in various technologies. For light current applications linear technology is popular since linear is known to have poor energy efficiency, but it forms a very cost effective solution, simple, compact and reliable. Switch mode technology becomes more energy efficient for higher currents and it has excellent efficiency which also allows it to consume very little energy and reduce the amount of heat which is produced. This type of technology has made high power applications such as battery chargers or amplifiers more compact and more cost effective when employed. Some applications might even prefer to use dc-dc converters to isolate supply rails from others and have regulars built in. Even transformerless technology, such as computer power supplies will at the last stage employ some form of regulator technology before presenting the supply voltage to the functional circuits. The voltage regulator will for all theoretical purposes form the last functional stage of a power supply before a very stable and low noise output DC voltage is supplied, positive or negative.
How the voltage depending resistance works?
There are two ways of looking at this question, depending on what you mean by 'voltage'.The first applies to the supply voltage, which is quite independent of a circuit's load resistance. In other words, changing the load resistance will have no effect on the supply voltage (within limits; for example, and extremely-low resistance might cause the supply voltage to collapse!).The second applies to any voltage drops, which are proportional to the resistance across which they appear. If, for example, you have a high resistance and a low resistance, in series, then the higher voltage drop will appear across the higher resistance.
