No, the transformer has to supply the load, whether it is light or heavy.

Is transformer an amplifier?
No. In an amplifier, Power Out > Power in. In a transformer Power Out ~= Power In (minus internal losses). An AC generator is more like an amplifier than a transformer.
What is percentage of transformer loss at no load condition?
major component of power loss in a transformer is secondary resistance.when transformer is operated under no load,no current flows through the secondary.so under no load conditions transformer has just very small megnetic losses.
What does LT stand for in power transformer?
Transformer Inductance?
What is the main different between the power transformer and voltage transformer?
Voltage Tarnsformer transforms only voltage. While power transformer transforms both voltage and current.
Can a a electric substation in a city use transformers to increase the power output?
No! A transformer changes voltage levels, not power levels. In fact, the output power of a transformer is actually a little lower than its input power, due to the efficiency of a transformer.
Which routers have power lights?
I would think ALL of them ! The power light is an indicator for the user that mains is present and the unit is switched on !
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
Why transformer action takes place in a DC circuit?
A: A transformer is a PASSIVE ac component applying dc to it the wires resistance would be the only limiter for current flow. Usually a common transformer will burn up fast or slowly depends on power applied

How can you get constant power to a receptacle after a light switch?
You'd need to branch the circuit before the switch. This can be immediately before the switch, in the box that holds the switch, but you can't get constant power from a switched circuit after its been switched.
What lights first when computer switched on?
On a desktop, the power button will usually light up. On a laptop, the power lights (located on the front of the laptop) will usually light up first.
What is the difference between power transformer and instrument transformer?
A power transformer is used to provide power (to your home, for example), an instrument transformer is used to measure voltage or current (for metering, for example).
What will happen you f the rated power of transformer is changed?
You cannot 'change' the 'rated power' of a transformer except by changing the transformer for another one. You can, though, operate the transformer below its rated power or, for short periods of time, operate the transformer aboveits rated power.
What happens when a light bulb is connected to the output coil of the transformer?
Assuming that the voltage rating of the lamp matches the rated secondary voltage of the transformer, the lamp will operate at its rated power.
What do you do when the Wii will not turn on?
If the power light is green, the console is already on.If the power light is red or yellow, try using the power button on the console(as opposed to the power button on the remote).If the power light is black, the power might be out, it might be switched off at the mains, or it might not be plugged in properly.
What is meant by the term transform?
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
What is on off switch?
Say it is a power circuit, a light bulb is bright from the battery, flowing through the wires and the light bulb. There is a switch controling the power that goes through, so if you switched the off switch off, the power will no longer be flowing through(the light bulb wouldn't be bright any longer).
