electric power
the rate at which electric energy is changed to another form of energy
series circuit
a circuit with just one loop for current to move through
charging by contact
transferring charges by touching or rubbing
charging by induction
when electrons on a neutral object are moved by a charged object
a material in which electrons can move easily
a material in which electrons can not move easily
law of conservation of charge
charge can be transferred from one thing to another, but it can not be created or destroyed
static electricity
the build up of charges on an object
a closed pateh that electric current follows
electric current
the rate at which charges move in one direction past one point
Ohm's law
the current in a circuit equals the voltage difference divided by the resistance
the tendancy for a material to oppose the flow of electrons, changing electric energy into heat and light
voltage difference
something related to the force that makes electric charges flow.
