number of charge carries Flashcards
1
Q
formula for power?
A
power (W) = voltage (V) x current (A)
2
Q
formula for enerfy?
A
energy (J) = current (A) x time (s) x voltage (V)
3
Q
equation to find charge of a circuit?
A
charge (q) = current (A) x time (s)
4
Q
what is drift velocity?
A
the average velocity attained by the electrons of a material
5
Q
what is charge carrier density?
A
denotes the number of charge carriers in per volume
6
Q
what equation is linked with current and drift velocity?
A
current - charged particle x cross sectional area x drift velocity x electron charge
