Answer 4

nAvQ
n- number density
A- cross
v-drift velocity
Q- charge

Question 5

elementary charge

Answer 5

1.6 x10 -19

Question 6

V=
Voltage/ potential difference

Answer 6

ΔW / ΔQ
W - energy transfered
Q - Charge

Question 7

R=
resistance

Answer 7

V= I x R

Question 8

Equations for power

Answer 8

P = VI
P = I(squared) x R
P= V (squared) / R
