Bioelectricity 1 Flashcards
1
Q
What is the difference between conductors and insulators?
A
Conductors have electrons that can move freely around the material, causing en electric current, while the electrons of insulators are tightly bound, and cannot move
2
Q
How can charge be transferred?
A
Friction, conduction, and induction
3
Q
What is meaningful about electric potential?
A
Differences in electric potential (voltage)
4
Q
What are equipotential lines?
A
Lines/surfaces where there is no work done on a charge as it moves along
Always perpendicular to electric field lines
5
Q
How can an insulator become a conductor?
A
If a high enough electric field is present (> 3 x 10^6 V/m)
