protons and neutrons
nucleus
charges that don't move easily through material since their electrons are tightly bound to the nucleus.
insulators
A force that opposes motion between two surfaces that are in contact
friction
the fundamental law of electrostatics stating that the force between two particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them
Coloumbs law
charges that move easily through the material, outer electrons are not as tightly bound to the nucleus. they conduct heat and electricity easily. ex): metal, fingers, etc
conductor
What is the unit for current
ampere
only allows electrons to flow in one way
Direct current
electrons move back and forth without appreciable movement
alternating current
what is the unit for resistance
ohms
uses mechanical motion to create electricity
generators
Continuous path for which charge flows
Electric Circuit
Rate of which energy is transferred in the circuit; 1 Watt
Power
example of electrical conductors
metal
force is measured in
newtons
charge is measured in
coloumbs
electric potential or also called
voltage
gain electrons, charge becomes
negative
unlike charges do what
attract
like charges do what
repel
A way to charge insulators and conductors
