Ciri-ciri arus ulang alik

Pilih 2

• Produce by dry cells

  Dihasilkan oleh sel kering

• The voltage can be reduced and increased

  Voltannya boleh diturunkan dan dinaikkan

• Generated at power station

  Dijanakan di stesen jana kuasa

• Flowing in one direction

  Mengalir dalam 1 arah

Bilangan lilitan gegelung primer kurang daripada bilangan gegelung sekunder

The number of turns of the primary coil is less than the secondary coil
