chapter 7 vocab


static electricity The accumulation of excess electric charge on an object.
Law of Conservation of Charge Charge can be transferred from object to object.
conductor A material in which electrons are able to move easily.
insulator A material in which electrons are not able to move easily.
Charging by contact The process of transferring charge by touching or rubbing.
Charging by induciton The rearrangement of electrons on a neutral object caused by a nearby charged object.
Electric current The net movement of electric charges in a single direction.
Voltage Difference is related to the force that causes electrical charges to flow.
circuit A closed path that electric current follows.
resistance is the tendency for a material to oppose the flow of electrons,changing electrical energy into thermal energy and light.
Ohms law the current in a circuit equals the voltage difference divided by the resistance.
series circuit The current has only one loop to flow through.
Parallel circuit contain 2 or more branches for current to move through.
electric power The rate at which electrical energy is converted to another form of energy.
