What is a transformer that increases voltage?
A transformer that increases voltage is a step-up transformer.
What is the different between et up and set down transformer?
the difference between a step up transformer and a step down transformer is that, in a tsep up transformer, the voltage secondary is greater than the primary side but in a step down transformer, the voltage secondary is lesser than the primary side
Why transformer is used?
A transformer used to step up or down the value of voltage.
How does conservator work in transformer?
To allow room for oil expansion and contraction. The transformer is completely filled with the oil and when it heats up under load or due to ambient temperatures, the oil has to have a place to go. In the event of colder weather or if the transformer is not under heavy load the oil cools and contracts creating a slight vacuum inside the tank. The conservator acts as a reservoir of oil that can then flow back into the tank so that no air enters it.
Which transformer raises the voltage high and lower the current for transmission?
A step-up transformer.
Why does radiation heats up?
Radiation never heats up .... when it is absorbed by matter then the matter heats up.
What losses can be measured in a short circuit test of a transformer?
Winding copper losses of a transformer can be measured in a short circuit test of a transformer. Impedance voltage is given to the primary and the secondary is often shortcircuited. (some times the reverse is done of this). Full load currents are made to flow in both primary and secondary circuits. This current flow heats up the 2 windings of the transformer. Power consumed at this time gives the transformer copper losses.
Which heats up faster by day?
The desert heats up faster.
How do you produce a step-up transformer in an ordinary transformer?
Transformer function is either to step-up or down the voltage. There is nothing like an ordinary transformer.
Which heats up fastest soil water air or sand?
Soil heats up and cools down the fastest. Water heats up regulary and does not cool down for a while. Sand heats up the slowest and cools down the slowest.
What is a transformer that increases voltage?
A transformer that increases voltage is a step-up transformer.
What is a transformer called that increases voltage?
A transformer that increases voltage is a step-up transformer.
What heats faster rock or soil?
Sand heats up faster
Does water heat up the least from the suns energy?
It heats up slowly, but hard to say it heats up the least.
What kind of transformer for going from 120v to 220v?
This type of a transformer is known as a step up transformer.
What is the transformer used in ups?
simple step up transformer
Step up transformer is used to increase the?
A step up transformer is used to step up an AC voltage
