How Electric power is transformed upon one coil to other coil in a transformer?

One coil builds up a magnetic field when it is energized (and de-energized) and this induces an electric current in the other coil. The voltage produced in the second coil is determined by the number of coils wound on it compared to the first coil. This is called the turns ratio and only works with alternating current unless you are using it with a dc battery to make a spark in an ignition coil.
examples primary 100 turns, secondary 200 , is a step up transformer
ie from 10 volts AC to 20 volts AC 100 turns primary, 50 turns secondary, step down transformer
ie from 10 volts AC to 5 volts AC

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.
Is a transformer one source of constant electric current?
A; Terminology is not correct a transformer is not really a source but rather a device to transform one source of power to some power that can be used as required minus efficiency of power transfer
What must happen to the electric current in power lines before it can safely enter your home?
step-down transformer
What kind of transformer is used to change the voltage of electric current in transmission lines before it enters houses in a neighborhood?
It's called a 'distribution transformer', as opposed to a 'power transformer' which is used in the transmission and primary-distribution electrical systems.
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.

Difference between power and furnace transformer?
Power transformer is used step up or down the voltage for the electricity transmission while furnace transformer is used to melt the metals and ores in the electric furnace.
What is the name of a step-up which increases the voltage of electric energy that is generated at a power?
An electrical transformer can step up (or step down) the voltage.

What we use of automatic Electric transformer use in power transmission?
"Electric" transformers are used in the electric power system for many things. I wonder if you mean "auto" transformer. Transformers are used to step up/down voltage and currents, to provide a ground reference, to inject signals onto power lines, to sample high voltages and currents, etc.
What is the use of transformer?
Transformer , device that transfers electric energy from one alternating current energy from one alternating current circuit to one or more other circuits , either increasing [ Stepping up ] or reducing [ Stepping down ] The voltage of convention power circuits to operate low- voltage devices , such as doorbells and toy electric trains . and to raised the voltage from electric power can be tansmitted over long distance
What happen to the heating element if lower power supplied to an electric kettle via transformer?
it won't get as hot
Can an electric transformer send too much electricity to the meter causing a high electric bill?
An electric transformer does not send electricity to the meter it supplies a source of power that is requested by the demand of the load. The meter is a device which totals the amount of power that you use. This is the amount that you are billed for. If your electrical bill is high only you can reduce it by decreasing the load demand.

What do electric substations do?
Electric substations either step up voltage or step down voltage for electric power distribution. For example, power being generated at a power plant would be stepped up in voltage for transmission over the electric grid. On the other hand, power coming into a residential neighborhood from the electric grid would be stepped down in voltage for distribution to individual homes. This increasing or decreasing of voltage will be accomplished by using transformers in the substation. There will also be electric circuit breakers in the substation located on both the high and low voltage sides of the transformer. These circuit breakers are used to be able to isolate the transformer from the electric grid for maintenance purposes or in case of an electrical fault that could damage the transformer. Most substations will also contain a Control House that contains all of the control equipment for the substation as well as battery backups in case of loss of power. Type your answer here...
