electrons will: random motion

part of the material loses electrons while the other
gains them, is called:

tor?
17. What real life similarity do free electrons in a conduc- cars of a long train
tor have? starting and stop-
ping together
18. The direction in which current flows in a conductor purely arbitrary as
is: long as it's used
consistently
19. In which direction do electrons flow in a conductor? negative to posi-
tive
20. What is the direction in which positive charge carriers conventional cur-
flow through a conductor? rent flow
21. What kind of flow is caused by electrons jumping hole flow
from one position to another?

circuit from the negative terminal of a power supply
to the positive terminal?
23. What kind of current carrier flows in a direction oppo- hole
site to electrons?

of electrons do not equal its number of protons?
25. What kind of current maintains the same direction of unidirectional cur-
flow? rent
26. What kind of current changes direction? bidirectional cur-
rent
