13.Resistance is:
A.
the opposition to current flow
accompanied by the dissipation of
heat
B.
symbolized by R, measured in ohms,
and directly proportional to
conductance
C.
directly proportional to current and
voltage

10.What happens to current and
resistance if the voltage doubles?
A.
Current doubles and resistance
doubles.
B.
Current doubles and resistance is
halved.
C.
Current remains the same and
resistance doubles.
D.
Current doubles and resistance
remains the same.
