How do you reduce a ripple voltage?

You reduce ripple voltage by adding a low-pass filter. In the simplest case, you put a capacitor after the rectifier. The peak voltage will be the rectifier output voltage less the forward bias of the rectifier, while the minimum voltage will depend on current and capacitance. In a more complex case, you could use an LC filter, making the peak voltage smaller. Specifics are dependent on the power and performance requirements.


How can calculate kw and kvar?

There are numerous ways of doing this; it depends on what information you are give to start with. One method is: power = apparent power x cosine (phase angle)reactive power = apparent power x sine (phase angle)(where apparent power = supply voltage x load current)


What is the formula for phase angle?

Phase angle is defined as the angle by which the load current leads or lags the supply voltage in an AC circuit. There are numerous ways to calculate a circuit's phase angle, so there is no 'formula' as such. For example, if you know a load's resistance and impedance, or its true power and apparent power, then you can use basic trigonometry to calculate the phase angle, and so on.


What is the difference between IPS and UPS?

Both of are power supply devices. But there are many difference between IPS & UPS. 1. IPS means Instant power supply, UPS means Uninterrupted Power system. 2. IPS backup system is so high, But UPS backup system is low 3. IPS use a large number of electronic equipment, But UPS use a small equipment 4. IPS provide large time backup, But UPS provide short time backup 5. For IPS must be use big size battery, But UPS is not. 6. IPS can be operate more than one electronic equipment like Computer, TV, Fan etc at a time, But UPS can be operate only one equipment.


What is power factor in electrical?

Ratio of voltage rating and current rating is called power factor in electricalAnswerPower factor can be defined in a number of ways -for example:cosine of the phase angleratio of true power to apparent powerIt has nothing to do with the ratio of voltage rating to current rating!

Which filter do you use to remove pulsations from a power supply output?

There is no answer to this. If a power supply pulsates, what frequency, etc. If a power output needs filtering there are oodles of ways to do it depending on the desired result and the starting conditions. A starting point is a big capacitor.

How do you check motherboards PCI power supply?

There is no such thing as PCI power supply. Case power supply can supply power to your PCI-E ports by means of 4, 6 and 8 pin connectors. It's especially true for new cards where PCI-E power is required to operate. Anyway, there are couple ways to test pins. One of them is to buy computer power supply tester. Second is cheaper is you have multimeter... You can test each pair of pins, required voltage is standardized and can be found in internet.


What are the ways to reduce loadshedding?

Ways to reduce load shedding include increasing energy efficiency measures, promoting renewable energy sources, upgrading and modernizing the power grid infrastructure, implementing demand-side management techniques, and diversifying the energy mix to decrease reliance on a single power source.


Which of the following strategies can help Earth's coal supply last longer?

Implementing carbon capture and storage technology to reduce emissions, increasing energy efficiency in coal-fired power plants, and promoting renewable energy sources as alternative to coal can help extend Earth's coal supply. Additionally, investing in research and development to find cleaner and more sustainable ways to use coal can also contribute to making the supply last longer.


Can you reduce consumption?

There are various ways that you can reduce energy consumption. One of the best options is using green energy like geothermal or wind power which will help in reduction of consumptions as well as preservation of the environment.


List the major types of water pollutants suggest ways to reduce the level of each type of pollutant in a water supply?

Some of the major types of water pollutants are chemical pollution, nutrient pollution, and microbial pollution. Ways to reduce microbiological pollution are by having facilities to clean the water. To reduce nutrient pollution stop using fertilizers and to reduce chemical pollution monitor companies more closely to stop them from dumping chemicals into the water.
