• Physics
• Electricity

for action at a distance

Electric fields
charge ←→ field ←→ charge

elektromos térerősség

a quantity to characterize electric fields

$\vec{E}=\frac{\vec{F}}{q}$
$[\vec{E}]=\frac{N}{C}(=\frac{V}{m})$

Electric field lines
can characterize both direction and magnitude

• laser printers
• inkjet printers
• electric desooting (koromleválasztás)
• electrostatic painting (sintering)

Around curved objects

around pointed parts of conductors electric field is stronger, it may ionise air particles, which then are repelled

• electric wind
• electrically charged channel

created by an emf source
