Why power at the secondary winding is less than the power at the primary winding?
If power were greater at secondary you would have an unlimited source of power. It is less because there are always losses in a transformer.
Why transformar primary refers to secondary?
All transformers contain both primary and secondary coils. The primary will refer to the secondary when the voltage is to high. As voltage increases, it passes down the power to the secondary for efficient distribution of power.
How do you calculate MVA rating of power transformer?
The product of the secondary rated current and the secondary rated voltage will give you the rated V.A of the transformer.
What is the current of a 45 kva transformer?
Presumably, you are asking what is the rated secondary current for a 45 kV.A (not 'kva') transformer? The answer depends on its rated secondary voltage. To obtain the rated secondary current, you divide the (apparent) power rating by its secondary rated voltage.
Have a step up tranformer. 110 volts to 220 volts. Power 550VA. Can I connect the secondary to 220 volts and get 110 volts form the Primary and use this 110 volts to run an equipment that draws 2 amps?
firstly please know what is ment by secondary and primary? primary-it means power is given to that port secondary-it means power is taken from that port you can use the transformer in any mode that meas you can give power to primary for taking power from secondry and vice versa. you can use the power delivered by the transformer from the secondry for any purpouse

What is Gladstone Park Secondary College's motto?
The motto of Gladstone Park Secondary College is 'Knowledge is Power'.
What are the limitations of power supply?
Power limitation transformer circuit structure of power supply, including: an electromagnetic interference filter unit, a rectifying unit, a power factor correction section, a transformer having a primary input terminal and secondary input terminal, a pulse controlling unit connected with the secondary input terminal of the transformer, a primary power limitation circuit and at least one secondary power limitation circuit, an output current controlling unit and an output voltage controlling unit. The input terminal of the output current controlling unit is connected with the secondary output terminal of the transformer. The primary output terminal and secondary output terminal of the output current controlling unit are respectively serially connected with the primary and secondary power limitation circuits. The input terminal of the output voltage controlling unit is connected with the secondary output terminal of the transformer. The output terminal of the output voltage controlling unit is connected with the secondary power limitation circuit for controlling the magnitude of the voltage and current of the primary and secondary power limitation circuits so as to control the output power.
How does a power mat for an Android device work?
The primary coil is in the power mat while the secondary coil is in the Android device. Power goes from the primary coil to the secondary coil, which allows the phone to charge.
Given a Transformer with 110vac at 1 amp applied to the primary with 1000 turns and the secondary of 500 turns what is the voltage current and power of the secondary?
Given a Transformer with 110vac at 1 amp applied to the primary with 1000 turns and the secondary of 500 turns what is the voltage current and power of the secondary?
What is meaning of apparent power in transformer?
Apparent power is the product of voltage and current in an a.c. system, and is expressed in volt amperes. The rated apparent power of a transformer is the product of its rated secondary current and rated secondary voltage.
When the transformer is connected to the power source the secondary current is 0 what is the possible fault in the transformer?
A secondary current of 0 would suggest to me that the secondary circuit is open. A normally operating circuit with zero current flow would be very unusual. No load in secondary circuit. No secondary current can also be attributed to the primary power source open or an open primary winding.
Can you replace a 5 volt power supply with a 10 volt power supply?
If the power supply has a 5 volt tap on the secondary side of the transformer, yes. If there is no tap and the secondary side of the power supply is only 10 volts then no, you can not substitute the higher voltage unit.
What principle of joint operations is to allocate minimum essential combat power to secondary efforts?
The purpose of this principle of joint operations is to allocate minimum essential combat power to secondary efforts
How do you calculate MVA rating of power transformer?
The product of the secondary rated current and the secondary rated voltage will give you the rated V.A of the transformer.
What is the number of turns in primary and secondary coil for 12 volt battery charger with 220 volt power supply?
what is the number of turns in the primary and secondary coil for 12 volt battery charger with 220 volt power supply> what is the number of turns in the primary and secondary coil for 12 volt battery charger with 220 volt power supply>
