Transformer is a device which is used for changing the voltage of an AC power source to higher or lower value.
Principle of transformer in physics
It is based on principle of mutual induction that is an emf is induced in a circuit due to a current changing in a neighbouring circuit.

Chemistry, a branch of physical science, is the study of the composition, structure, properties and change of matter.
Chemistry is chiefly concerned with atoms and their interactions with other atoms - for example, the properties of the chemical bonds formed between atoms to create chemical compounds.
Chemistry is sometimes called "the central science" because it bridges other natural sciences like physics, geology and biology with each other.
Chemistry is a branch of physical science but distinct from physics.
Etymology
The word chemistry comes from the word alchemy, an earlier set of practices that encompassed elements of chemistry, metallurgy, philosophy, astrology, astronomy, mysticism and medicine; it is commonly thought of as the quest to turn lead or another common starting material into gold.
Alchemy, which was practiced around 330, is the study of the composition of waters, movement, growth, embodying, disembodying, drawing the spirits from bodies and bonding the spirits within bodies
An alchemist was called a 'chemist' in popular speech, and later the suffix "-ry" was added to this to describe the art of the chemist as "chemistry".
The word alchemy in turn is derived from the Arabic word al-kīmīā (الکیمیاء). In origin, the term is borrowed from the Greek χημία or χημεία.
This may have Egyptian origins.
Many believe that al-kīmīā is derived from the Greek χημία, which is in turn derived from the word Chemi or Kimi, which is the ancient name of Egypt in Egyptian.
