• They are just as concentrated as the middles.

• They have a high concentration, only on one end.

If a length of wire carrying a current is bent to form a loop, the lines of force around the conductor will leave at one side of the loop and enter

• on the same side

• on the opposite side

• on the east side

• on the west side

What is the symbol for current flow?

• J

• k

• l

When two points of unequal potential or voltage are connected

• current flows

• no electromotive force exists

• current ceases to flow

• electrons move at different times

Joining RV batteries in series allows the technian to

• keep the same amperage and voltage

• keep the same amperage and add voltage

• add both voltage and amperage
