1

friction

method of charging - rubbing two things together, one thing sheds electrons

2

contact/conduction

a charged obj touches another ad charges are conducted/transferred

3

induction

object is polarized and then grounded or separated into parts

4

electric field

alteration of space around an electric charge

5

electric field lines

imaginary lines drawn to visualize the electric field
point away from positive charge and toward negative charge

6

electric field vectors

if you place another charge in an electric field created by a source charge, it will experience a force

7

opposite charges in electric field

force and field will be opposite ways

8

conventional current

positive charge moves toward negative charge

9

electron current

nonequilibrium motion of charged sustained by an internal electric field - or the rate at which electric charges pass through a cross sectional wire

10

actual current

negative to positive

11

direct current

same current direction at all times

12

alternating current

2 wires - switches which wire is pushing in

13

factors affecting resistance of a wire

length (long=more), area (larger=less), material, temperature (high=more)

14

electric power

the rate at which charge carriers do work

15

short circuit

when a wire is connected from 1 terminal of a battery to another by a wire with little resistance (results in insulation merits or fire)

16

electromagnetic force

energy per units charge supplied by source of electric current
