How a transformer is very useful in ac supply?
Transformer is the only device which is capable to stepup or stepdown an ac signal. That's why its used widely in ac supply.
Why not stepup transformer is not used in rectifiers?
Rectifiers turn A/C into D/C, but transformers can only run on A/C.
What is stepup transformer?
A step-up transformer produces a voltage across its secondary winding which is higher than its primary winding. The secondary winding is connected to the load, while the primary winding is connected to the supply.
What is transformer w?
Transformer is a electric device which it can be used for to transfer the ac current one circuit to another i.e. To reduces voltage and without frequency changing. Many types of transformer available in various purpose i.e. Stepup transformer, stepdowntransformer ,autotransformer ,,,,,,,etc answered by arivukkarasu.a
What is the efficiency of a transformer?
The "all day" efficiency of a transformer is defined as the ratio of energy out/energy in for a given all day cycle.
Does a transformer convert mechanical energy to electrical energy?
No. A transformer doesn't source or sink energy, or convert energy from one form to another.The ideal transformer merely changes the parameters of an electrical current, with no effect on energy levels.A non-ideal (real-life) transformer decreases the energy in the electrical circuit, because its lossesrob some of the energy and turn it to heat.
What does a step up transformer increase?
Power is normally transmitted at high voltage through step up/step down transformers to minimize the power losses in the transmission lines (this is one reason anyway). Since power loss is equivalent to the resistance of the conductor times the current squared, stepping up the voltage by a factor of two cuts the transmission losses by a factor of (2^2 = ) 4.
What is and example of change electrical energy to electrical energy?
A transformer.
What is the difference between step up and step down?
in transformers for instance a stepup transformer does exactly that, steps up the voltageAND/OR theamperage and a step down transformer reduces the same. if you have a machine that operates on say 120 volts alternating current single phase and your building or power supply in your buildingis set up for or delivers480 volts alternating current-three phase you will need a step down transformer to operate the machine.
Does a transformer provide electrical energy that is produced chemically?
No. A transformer transforms electrical energy, from one voltage to another voltage.No. A transformer transforms electrical energy, from one voltage to another voltage.No. A transformer transforms electrical energy, from one voltage to another voltage.No. A transformer transforms electrical energy, from one voltage to another voltage.
How much energy is used by a transformer?
An efficient transformer will convert more than 99% of the input energy into output energy, therefore wasting less than 1%.
How energy is transformed in a transformer?
Its transformed into work!
