Assuming you're asking about an electrical transformer...
Electricity meets resistance as it flows threw the transformer. Some of the flow of the energy is converted to heat due to the resistance and you get less electrical energy out than you put in. Think of electrical resistance as similar to friction between two objects, say rubbing your hands together quickly and generating heat.

Does a refrigerator have 100 percent efficiency?
nothing has 100% efficiency.
How many primes are less than 100?
There 25 primes less than 100: 2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67,71,73,79,83,89,97.
How can you tell whether the percent of a number will be greater than less than or equal to the number?
100% equals the number. Less than 100% is less than the number. Greater than 100% is greater than the number.
What is the largest integer less than or equal to -100?
The largest integer equal to -100 is -100. The largest integer less than -100 is -101.
What prime number or number less than 100 are even?
There are 49 even numbers less than 100, but only the number 2 is an even prime number less than 100.
What would cause the calorimeter efficiency to be less than 100 percent?
why is the efficiency of a calorimeter less than 100%
Can any pulley have a efficiency over 100?
No. A perfectly frictionless machine could have an efficiency of 100%. Anything less perfect must have can efficiency less than 100%.
What is efficiency always less than?
It is always less than 1 or 100%.It is always less than 1 or 100%.It is always less than 1 or 100%.It is always less than 1 or 100%.
Why is efficiency less than 1?
The Law of Conservation of Energy states that energy can't be created or destroyed. Thus, efficiency is 1 (i.e., 100%) if there is a perfect energy conversion. Since this is usually not the case, and some energy is wasted, the efficiency of most energy conversions is less than 100% (or less than a factor of 1).
What is the efficiency is the output work is 12000 and the input work is 15000?
Efficiency as a percent is output/input * 100%12000/15000 * 100% = 80% efficiency which makes sense, because it takes more work (input) than it give out (output). So the efficiency should be less than 100%.
If the output work of a simple machine is than the input work the machine is said to have less than 100 percent efficiency?
input
The efficiency of an actual machine is always less than what percent?
It is always less than 100% Theoretical machines can have efficiencies of 100% but in practice there is always some energy loss Efficiencies of more than 100% are not allowed by the laws of thermodynamics!
What is meant by efficiency of a machine?
It is the output energy compared to the input energy. This will always be less than 100%
Does the input and output frequency of the transformer is the same?
For an 'ideal' transformer operating at full load, the answer is yes. But, 'real' transformers are a little less than 100% efficient so, in practice, the input power will slightly exceed the output power. In most circumstances, for the purpose of calculating primary and secondary currents, we can assume 100% efficiency.
Why is it that efficiency of a machine is less than 1?
The efficiency is always less than one because some of the energy is always useless for what you want. Most wasted energy eventually turns into heat. therefore the efficiency is like a percentage with 1 being 100% a device can't be 100% efficient as some energy is wasted. To work out the efficiency of a device you need to do the total useful energy produced divided by the total energy that is inputted into the device
Why is the efficiency of a machine less than 1?
An efficiency factor of 1 (or 100% efficiency) is not possible due to losses that cannot be reduced to zero. These losses take the form of friction, heat loss etc.
What stronger work output or work input?
In theory, work output might be equal to work input; that would be 100% efficiency. In practice, the output of a machine will be less than the input; i.e., some energy will be lost.In theory, work output might be equal to work input; that would be 100% efficiency.
