Pls solve Q.54
Q.54. Which is true about Piezoelectric crystals?
(1) They produce an electric current on heating
(2) They produce an electric current when a mechanical stress is applied
(3) They are insulators
(4) They are magnetic in nature
Dear Student,
Answer 2 is correct as,
A piezoelectric substance is one that produces an electric charge when a mechanical stress is applied. or example the stone used in watches are piezoelectric in nature, which generate current on mechanical stress to run the watch machinery.
