Is a transformer a source of constant electric current?
A; Terminology is not correct a transformer is not really a source but rather a device to transform one source of power to some power that can be used as required minus efficiency of power transfer

What happens to voltage when current is increased?
current is decreased Depends of the circuit or device: in a stepdown transformer: power in= power out, V x I = V x I , Increase voltage in (power remaining constant) you current output will increase.
4 What is the difference between a transformer and a rectifier Which are found in a PC power supply?
A rectifier is a device that converts alternating current to direct current. A transformer is a device that changes the ratio fo current to voltage. A rectifier is found in a PC power supply.
What is the difference between a transformer and a rectifier Which are found in a PC power supply?
A transformer is a device that changes the level of an a.c. voltage, while a rectifier is a device that converts alternating current to direct current.
Explain differancnce between instrument current transformer and measuring current transformer?
Current transformer is a device used to measure the flow of current through a power system and the measured current is inputted to a protective relay system. It is used to detect system malfunction. Current transducer is a device used to measure AC and DC current based on the halt-effect technology.
What device is needed to convert 110 to 220 volt?
For higher current applications you would need a power transformer, for lower current applications you would need an adapter transformer.
What is the significant relationship of the no load loss in excitation current test in transformer?
The no load losses are the losses caused by energizing the transformer. These are constant losses, regardless of loading. This in effect tells you the efficiency of the transformer. (Power in) - (no load losses) = (Power out)
What is the difference between a current transformer and a voltage transformer?
A current transformer step downs the current in a power circuit to a lower amperage. A voltage transformer steps down the voltage in a power circuit, typically to 110 volts AC for residential and business use.
Can you use transformer in place of amplifier?
A transformer is a passive device while an amplifier is an active device. a transformer can amplify voltage but never power WHILE AN AMPLIFIER CAN amplify power's can you use it sure withing the limitation of the transformer and only to amplify volts.
Magnetic inrush current in power transformer with waveforms?
The mgnetic inrush current is the current drawn by the transformer when power is applied to the primary winding
Is current ratio of transformer constant on loads?
the current ratio I1/I2 is a constant for all loads. the total current drawn on the secondary winding of a transformer depends on the total circuit impedance as seen by the transformer output terminals. considering that the power in primary is equal to the power in the secondary and is a constant (assuming no losses as per the principle of conservation of energy). The input voltage(primary) is a constant i.e equal to the primary distribution line voltage, and the secondary distribution line voltage is also operated at a constant value. therefore KVA(primary) = KVA( secondary) V1I1=V2I2 I1/I2 =V2/V1 which is a constant irrespective of the load.
