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.

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.
Does a refrigerator have 100 percent efficiency?
nothing has 100% efficiency.
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%.
What is the efficiency of a transformer that has an input of 600 VA and an output to a load of 580 VA?
The efficiency of a transformer is calculated by dividing the output power by the input power, then multiplying by 100 to get a percentage. In this case, the efficiency would be: (580 VA / 600 VA) * 100 = 96.67%. This means the transformer is operating at around 96.67% efficiency.
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
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 input work the machine is said to have less than 100 percent efficiency?
No, a simple machine with less output work than input work is said to have less than 100 percent efficiency. Efficiency is a measure of how well a machine converts input work into output work, with 100 percent efficiency meaning that all input work is converted to useful output work.
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.
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%
How does the output work compare to the input work for a machine that has an efficiency less than 100?
For a machine with efficiency less than 100%, the output work will always be less than the input work. This is because some of the input work is lost as waste energy due to factors like friction, heat, or other inefficiencies in the machine. The efficiency of a machine is a measure of how well it converts input work into useful output work.
The efficiency of an actual machine is always less than what percent?
The efficiency of an actual machine is always less than 100 percent, as no machine can convert all input energy into useful output energy due to factors like friction, heat loss, and inefficiencies in the system.
