Question | Answer |
---|---|
is the accumulation of excess electric charge on an object. | Static Electricity |
states that share can be transferred from object to object, but it cannot be created or destroyed | Law of Conservation of Charge |
surrounds every electric charge and exerts the force that causes other electric charges to be attracted or repelled. | Electric Field |
is a material through which electrons move easily. | Conductor |
is a material in which electrons are not able to move easily. | Insulator |
is the process of transferring charge by touching or rubbing. | Charging by Contact |
the rearrangement of electrons on a neutral object caused by nearby charged object. | Charging by Induction |
is a device that can detect electric charge. | Electroscope |
is the net movement of electric charges in a single direction. | Electric Current |
is related to the force that causes electric charges to flow. | Voltage Difference |
is a closed path that electric current follows. | Electric circuit |
is the tendency for a material to resist the flow of electrons and to convert electrical energy into other forms of energy. | Resistance |
the current in a circuit equals the voltage difference divided by the resistance. | Ohm’s law |
is an electrical circuit with only one branch. | Series circuit |
contain two or more branches for current. | Parallel circuits |
is the rate at which electrical energy is converted to another form of energy. | Electrical power |
