2. A TRANSDUCER IS DEVICE WHICH TRANSFORMS A NON-
ELECTRICAL PHYSICAL QUANTITY (i.e. temperature,light,
pressure) INTO A ELECTRICAL SIGNAL(i.e. voltage,current,
capacity ).
IN OTHER WORD IT IS A DEVICE THAT CAPABLE OF
CONVERTING THE PHYSICAL QUANTITY INTO
PROPORTIONAL ELECTRICAL QUANTITY SUCH AS
VOLTAGE AND CURRENT.

4.  TREANSDUCER IN WHICH ELECTRICAL PARAMETER i.e
resistance,inductance or capacitance CHANGES WITH THE CHANGE IN INPUT
SIGNAL , ARE CALLED THE PASSIVE TRANSDUCERS. THESE
TRANSDUCERS REQUIRE EXTERNAL POWER SOURCE FOR ENERGY
CONVERSION. IN SUCH TRANSDUCERS ELECTRICAL PARAMETERS i.e
resistance ,inductance or capacitance CAUSES A CHANGE IN VOLTAG
,CURRENT OR FREQUENCY OF THE EXTERNAL POWER SOURCE.
 PASSIVE INDUCTIVE TRANSDUCER.
