Transformer is a static device which transfer
the power from one circuit to another circuit without
change in frequency.

Answer / raj

transformer transfer the power from one circuit to another
circuit without change in frequency (it does not converts
the power to any other...it just transform the power)

Answer / prabhakar

Transformer is a static device wich transfers electrical
supply from one place to another place at the same frequency

Answer / b.suresh

Transforer is a static device, which transfors electrical
energy(v&i)from one circuit to another circuit without
chaining frequency.

Answer / ajmal

transformer has two winding, one is primary winding another
one is secondary winding, secondary winding have less
number of turns compare to primary, In transformer
secondary winding is shorted, in beteween the two winding
core is placed

Answer / vishwa sarathy

Transformer is a static device which transforms energy from
one circuit to another circuit at constant frequency

Answer / subra

transformer is a device which convert the voltage and
current. Its convertion is directly proportional to voltage
and indirecly proportional to current formula=
N1/N2=V1/V2=I2/I1

I have a shop heater with a 1/3 hp capacitor start, induction motor driving the fan. Intermittently, the fan motor speeds up significantly for several seconds (15-60 sec) then slows to normal operating speed. The manufacturer suggested changing the capacitor which made no sense, but I did it to no avail. Could this possibly be caused by the centrifugal switch intermittently reconnecting the start winding?
