The principal of a transformer is based on the principle of electromagnetic induction.

• Transformers work on the principle of Faraday's law of electromagnetic induction.

• When an alternating current flows through the primary coil, it creates a changing magnetic field.

• This changing magnetic field induces a voltage in the secondary coil, resulting in the transfer of electrical energy.

• The ratio of the number of turns in the primary coil to the number of turns in the secondary coil d...read more

M-25 is a mix design of concrete with a compressive strength of 25 N/mm².
