Alternating current
Videos
Alternating current is an electric current that periodically reverses direction and changes its magnitude continuously with time, in contrast to direct current, which flows only in one direction. Alte
Transformer
…in 1831, describes the induced voltage effect in any coil due to a changing magnetic flux encircled by the coil. Transformers are used to change AC voltage levels, such transformers being termed step-up or step-down type to increase or decrease voltage level, respectively. Transformers can also be…
