Static Electricity And Conduction Flashcards
1
Q
Where can static electricity be produced?
A
Can be produced by contact, friction or induction
2
Q
Thermionic emission
A
When the cathode warms up, the electrons will then become a cloud which are free electrons
3
Q
What are the effects of conduction of electricity?
A
Heat and Magnetic field in 100% of cases
Light in some gases
4
Q
How do you work out current density?
A
Current density (a/mm^2) = Current (A) / Cross sectional area (mm^2)
