Electricity can be represented by the flow of which of the following?

a. Negative ions through a nonconductive path
b. Negative ions over a nonconductive circuit
c. Electrons through a piece of copper wire
d. Electrons in a bidirectional path

Question 2

Placement of postconstriction extensions in a tube can deflect a flow 180 degrees along a new wall contour. This phenomenon illustrates the:

Answer to Question 1

ANS: C
Electricity is produced by the flow of electrons through a conductive material such as copper. Electricity cannot flow through nonconductive material or simultaneously run bidirectionally along the same path.

Answer to Question 2

ANS: A
Coanda was able to demonstrate that, with careful placement of the postconstriction extensions, he could deflect a stream of air through a full 180-degree turn by extending the wall contour.
