the current decreases.
AnswerThe secondary current is determined by the secondary voltage and the load, not by whether the transformer is a step-up or step-down type. Once this is established, you can determine the primary current. Remember, the secondary current determines the primary current, not the other way around!

What is the difference between ideal transformer and practical transformer?
There are basically 4 major differences :- 1. The windings (both primary and secondary) of an ideal transformer are considered to have zero resistance, hence the transformer is lossless. 2. There is no leakage flux in an ideal transformer. 3. The permiability of the core material in ideal transformer is considered to be tending to infinity and hence the current needed to set up the flux in the transformer is negligible. 4. There is zero hysterisis and eddy current losses in an ideal transformer.
What is leakage current in transformer?
In low voltage and electronics Leakage Current is any current that flows when the ideal current
What happens to the current if the potential difference is stepped-up in an ideal transformer?
In an ideal transformer, if the voltage is stepped up by a factor of x, then the current is stepped down by a factor of x. The end result is that the power, P=VI, is not changed. Again, this is in the ideal case.

What is the use of ideal transformer?
Ideal transformer is useful in understanding the practical transformer..i does't have losses...
What is meant by the term ideal transformer?
ideal transformer is that which has no power losses.if any transformer transfer power to secondary without power loss then that call a ideal transformer
How do you calculation power in a transformer?
In an ideal xmfr, the power in equals power out and only the voltage and current changes.
What is the angle between no load current and the applied voltage in an ideal transformer?
A: Transformer by itself goes not alter the phases the output can be in phase or out of phase depending how you look at it.
What happens to the current flowing in the ring main as more bulbs are turned on at night?
As more light bulbs are added in a series circuit, the effective resistance of the circuit increases. That causes the current leaving the source to decrease.
What is mean by 2is to 3 turns ratio Transformer what is primary turns and secondary turns?
with an ideal electrical transformer with an input current of 2 amps and an output current of 1 amp what is the turns ratio of the secondary and primary coils
Why transformer is not called an amplifier?
In an ideal transformer the power in equals the power out there is no gain. In an ideal amplifier the power out equals the Gain *Power In. An ideal transformer transforms energy at a ratio of its windings. For example an ideal 1:10 ratio transformer (step up) would convert a 10Volt input at 10amps to a 100Volt output at 1Amp. Or conversely an ideal 10:1 ratio transformer (step down) would convert a 10Volt 10Amp input into a 1Volt 100Amp output. Since Power = Voltage * Current we can see the power in equals the power out in an ideal transformer. In an ideal amplifier the power out is greater than the power in. This is defined as the gain of the amplifier. An ideal amplifier with a Voltage gain of 10 would take a 1Volt 1amp signal and amplify it into a 10Volt 1 amp signal. An ideal amplifier with a Current gain of 10 would take a 1Volt 1Amp signal and amplify it into a 1Volt 10 amp signal. Since Power = Voltage * current we can see the power in is less than the power out showing a gain in power.
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.
