Why instead of transmitting maximum power power utility transmits power at maximum efficiency?
This question relates to the economic decisions that electricity utilities make in designing their power networks. During peak load periods, power is transmitted at the maximum current that is safe for the network, but at other times power transmission simply depends on demand. Ideally, utilities would transmit power at maximum efficiency because, by minimising losses over the lines and in transformers, they minimise generation costs. However, each increase in efficiency results in increased capital costs. A compromise is always made between purchasing efficient power transformers and distribution transformers or less expensive ones with higher losses.
Does a microwave always need a dedicated circuit?
No
What two things do you always need for a circuit?

Why sf6 circuit breaker is mostly used in substations rather than other?
Rather than where? Circuit breakers are always located in substations.
Is it always advisable to operate at maximum power transfer condition?
yes
Why are distribution transformers frequently designed to develop maximum efficiency at loads that are somewhat lower than rated value?
It is always desirable to run any equipment or device at maximum efficiency for that matter, not only the power transformer. Power transformer maximum efficiency occurs when copper loss is equal to iron loss. (or no load loss equals to load loss). This does not necessariliy mean that maximum efficiency occurs at maximum or full load. Generally the maximum efficiency occurs at relatively less than full load of the transformer.
Efficiency of price mechanism in allocating resources?
Why the price mechanism is not always efficient at delivering public goods, merit goods and de-merit goods
Why are managers important to an organization?
He gets things done. He manages the work, staff, and administration and strives always for maximum efficiency and savings.
What is job efficiency?
Job efficiency is the rate at what you pay out for production versus the rate of profit you make. Companies are always looking for more efficient ways of creating products or delivering services. They focus on their job efficiency rating to cut costs to deliver these products and services so they collect more in profit.
Is it always a good idea to discard low efficiency?
No...... Not always........... They can be modified to high efficiency..............
Is it always a good idea to discard low efficiency devices?
No...... Not always........... They can be modified to high efficiency..............
What is the maximum efficiency can be?
Ideally 100%. But unless the only intended product is heat, practically it will always be lower. How much lower one would have to know much more than is given in this question.
Why can efficiency never can be 100 percent?
The laws of thermodynamics imply that there will always be some loss of efficiency.
Why a normal machine could not have the mechanical efficiency of 100?
Because there is always going to be friction, the efficiency of any machine will always be less then 100 percent.
What is the maximum sound?
There is no theroetical maximum sound. It can always get louder
Is a switch needed to make a circuit work?
Not always. Depends on the circuit.
