Chapter 8 - Charge and Current Flashcards
1
Q
What is the Equation for Electric Current, factoring in mean drift velocity?
A
2
Q
What is the difference between electron flow and conventional current?
A
Electrons flow from the negative to the positive terminal
vs
Current flows from the positive to the negative terminal.
3
Q
What is the net charge on an object?
A
4
Q
In what direction does charge and electrical current travel?
A
5
Q
What is Kirchhoff’s first law?
A
6
Q
Define number number density.
A
The number of free charge carriers per unit volume is the number density. The unit is n m⁻³ where n is number of electrons, and m³ is metre cubed.
7
Q
Define drift velocity.
A
Drift velocity is the average velocity attained by charged particles.
