What happens if transformer wattage is much less than load wattage?

If the load current is too high, the power lost in the transformer windings will be too high and it will overheat.
If the voltage is excessive, the power lost in eddy currents in the magnetic core will be too high and it will overheat.

If increase load of secondary side of transformer. why primary side current increases?
The wattage must remain equal on the primary and secondary sides of a transformer. An example to the above statement with a 1000 watt step down transformer. To fine the watts (load) the formula is W = A x V. The primary side of the transformer has the capacity of 1000 W = 4.16 Amps x 240 Volts. The secondary side of the transformer has the capacity of 1000 W = 8.3 Amps x 120 Volts. Using the transformer to its maximum, without overloading it, the primary will be 4.16 amps at 240 volts and the secondary will be 8.33 at 120 volts. As you can see the wattage (load) remains constant only the voltages and current change.
Can i Over load an oil filled transformer?
Any transformer can be overloaded by applying a load above the capacity rating of the transformer.
Can you load a transformer by a pure capacitive load?
No
What is zero current transformer?
It is a transformer with No load attach to it.
Why less current increases in transformer than in induction motor when load is increase?
The current flowing through a transformer's secondary is the current drawn by the load, so it will be exactly the same as the current flowing through your induction motor -assuming that is the load. Don't really understand the point of your question!
Will a 30 watt transformer damage a device needing only 15 watts?
No, the rating of the transformer, in watts, is the maximum amount of energy that can be safely drawn from the device. Any wattage load up to that limit is safe to connect as long as the voltage is correct to the load.
Is a transformer load inductive or capacitive?
A transformer is fundamentally a set of coils; therefore, a transformer is an inductive load. However, by "transformer load", you seem to mean "the load that is connected to a transformer". Whether that load is inductive or capacitive depends mostly on what is hooked up to the transformer.
Can you use a 1000watts transformer with a 700 watts appliance?
Transformers are sized by the secondary connected load. If the wattage of the load is not given, use the following equation to find it. Watts = Amps x Volts.
If increase load of secondary side of transformer. why primary side current increases?

Does a 600 watt garden lights transformer pull 600 watts all the time or just the load from the lights you have on it?
Watts are power. If the lights were mostly or totally switched off, you'd have a circuit generating 600W of heat somewhere if the transformer still took 600W, not only that, but when you switched on, the 600W that the transformer was consuming, would not disappear, so the total drain would be 1.2kW. ---- Don't understand the above answer. The 600 watts on the transformer nameplate is the maximum amount of wattage that the transformer can produce and still be within its safety limits. It doesn't draw that wattage all the time. If you had two 50 watt lamps connected to the transformer then the transformer has the capacity of 500 watts left. The transformer will only produce the wattage that the load requests. The transformer has the ability to supply twelve 50 watt bulbs. 12 x 50 = 600. Any more bulbs than 12 and the transformer is in an overload condition.
Difference between off load transformer and on load transformer?
Hope this helpsAn "OFF-Load tap transformer" can only have it's tap adjusted when it is De-energized,while the "On-Load tap transformer" can adjust its tap under load conditions.Kind RegardsHammad KhanUniversity of Western AustraliaAnswerAn 'off load' transformer is one whose secondary is open circuited, and not supplying a load. An 'on load' (not 'load') transformer is one that is connected to a load.
Can you sub a 240 volt 1.5 amp transformer in place of a 240 volt 3 amp transformer?
If the load you are connecting to the transformer uses 1.5 amps or less, yes.
How do you load a transformer?
Anything that draws energy from a supply is a load. So you 'load' a transformer by attaching a lamp, a motor, etc., to the transformer's secondary windings.
What happens when transformer is overloaded?
it trips the breakerAnswerThe transformer will overheat. But this is not necessarily a bad thing, providing the transformer is also allowed to operated below load, during which time it can then cool down. This cycle of overload/below load operation is quite usual for distribution transformers.
Can i Over load an oil filled transformer?
Any transformer can be overloaded by applying a load above the capacity rating of the transformer.
No-load and full load transformer?
A: a transformer will follow the rule of input output ratio with no load. As soon as a load is applied there will be changes in the ratio
Can you load a transformer by a pure capacitive load?
No
