number of tomes the electrons vibrate per second in a.c?

Answer 1

Since a tome is a book and made of paper which is an insulator. An electron under either AC or DC potential would not have any effect on a tome

AC is 60 Hz (Hertz - a unit of frequency) which means that the direction of current flow changes direction back and forth 60 times in a second.


60Hz Alternating Current (AC) is a standard frequency in the US and many parts of the world. However other countries may use 50Hz as their standard. 50Hz is widely used in Europe.
