Electric Field
Oops! This image does not follow our content guidelines. To continue publishing, please remove it or upload a different image.
An electric field is the region around a charged particle. Here, a force would be exerted onto other charged particles or objects. Required Practicals: I-V Curves: circuit with resistor - variables are potential difference and current - resistance increases in ohmic components as temperature increases. Resistance of a Wire: circuit with ammeter and voltmeter - increase gage (width)=lower resistance, increase length=raise resistance, increase temperature= raise resistance, material=lower/raise - eg copper wire has a low resistance.
