Review concepts of AC

......................... ....................... is an electric current which periodically reverses direction and changes its magnitude continuously with time, in contrast to ........................ .....................

what is it?

max Voltage of ac is .................. A

RMS of this p.d is ................. V

• less than 0.5 A

• 0.5 A

• 0.7 A

• 1 A

• less than 05A

• 0.5A

• 0.7A

• 1A

AC is converted into DC using a rectifier circuit. However, the converted DC is an unstable current that includes ripples. A capacitor is used to remove these ......................... and maintain a ................... voltage.

The ..................... core of a transformer is laminated to reduce ........................ currents.

What is Transformer?

• Transformer is a device used to convert alternating current to direct current
  

• Transformer is a device used to convert low alternating current to a high alternating current

• Transformers are used only for low alternating voltage

• Transformer is a device used to convert low alternating voltage to a high alternating voltage
