Alternating voltage

Devices which is used to convert high alternating current to low alternating current is …………………

A device that increases the voltage of an alternating current is called a(n)

Name two appliances/devices in which an alternating current is used.

(I) : In some AC generators, converts electrical energy into mechanical energy. (II) : A Transformer converts high voltage (low current) into low voltage (high current ) and vice versa. Which one is incorrect statement ?

Consider the following two statements A and B and identify the correct answer. (A) In a transformer a large alternating current at low voltage can be transformed into a small alternating current at high voltage (B) Energy in current carrying coil is stored in the form of magnetic field.
