Answer the following questions without referring to the material just presented. Begin the next section when you are confident that you understand what you’ve already read.

Name two characteristics that are common to every magnet.
____________________________ and
______________________________

A magnetic field consists of flux lines. Flux lines are also referred to as lines of ________________.

Electromagnetism is an interaction between a magnetic field and a voltage source.
TRUE FALSE

Use the right hand rule to determine what direction the current is flowing in the conductor shown to the right. Draw an arrow on the conductor to show your choice of direction.

A sine wave is used to represent alternating voltage as well as alternating current.
TRUE FALSE

With alternating current, electrons flow back and forth, changing direction very quickly.
TRUE FALSE

The number of cycles alternating current goes through in one second is known as the _______________________.

On the illustration below, indicate what direction current is flowing in the conductor marked “X” by drawing an arrow in or near the conductor, showing the direction. (Use Conventional Flow Theory.)

The peak value of an AC voltage or current occurs twice each cycle.
TRUE FALSE

Another name for effective value relative to AC current or voltage is ______________ - ______________ - ______________ value.

If we know the RMS is 240 volts and it is approximately 0.707 times the peak voltage, what would be the approximate peak voltage for this effective voltage?
