How can capacitor smooth or reduce the ripple of the voltage produced by the rectifier?
when rectifier is on, the capacitor is almost transparent (it charges to the voltage provided from the rectifier) when rectifier is off, capacitor holds the peak voltage since it stored a charge during rectifier on time.
How do you connect a dynamo and a turbine?
It can be a simple mechanical joining of the two shafts, so that when the turbine shaft rotates, the joined dynamo also rotates at the same speed. It is more common to use a gearbox, so that a different rotation speed is imparted to the dynamo. The ratio will depend on the ideal speed required by the dynamo and the available power from the turbine. A relatively slow moving set of wind turbine blades, will have a lot of available power, so a gearbox that has a large gear turning a small one, will increase the speed, allowing the dynamo to produce the required voltage. A water turbine may spin at a very fast speed, beyond the working parameters of the dynamo. In this case the gearbox will not only reduce the revs to the dynamo, but it will also be able to take a heavier load.
How must the voltage across a resistor change to reduce the current in the resistor by a factor of 3?
The voltage must reduce by the same factor - that is Ohm's law.
How is 4160 voltage made?
Well first we need to generate voltage from electrical generator. Then if voltage are below 4160 volt step up Transformer is used and if voltage are above 4160 volt step down Transformer is used. Generally voltage produced from generator are low so we need to step up voltage to higher values such as 240 kilo volt to transmit them to longer distances to reduce power losses.
How you can reduce voltage of a transformer?
Number of turns in the secondary winding define the voltage. Change the number of turn to change the voltage.
What are grid station?
Grid stations are the station which reduce the High Voltage to Low Voltage and increase the Current, the Current is Low and Voltage is High at the Generation Plant to reduce the energy losses during transmission of Electricity.
How you can reduce voltage without use of transformer?
a resistor
What can be used to reduce to current in a circuit?
A: Any resistance added in series will reduce the current unfortunately will also reduce the voltage
What can be used to reduce a current in a circuit?
A: Any resistance added in series will reduce the current unfortunately will also reduce the voltage
What affect does diet have on mold allergies?
Certain homeopathic ideologies would suggest that diet is a key factor in allergies. For example, if a person is allergic to trees and grass, a homeopath might suggest to eat locally produced honey to reduce those effects.
A device that decreases voltage?
Step down transformer, potentiometer or rheostats can all be used to reduce voltage.
What is a voltage droop used for?
The purpose of a voltage droop is to intentionally reduce the voltage of a device. Further information about why and when one would do this can be found on Wikipedia.
