### Physical Science equations for chapter 6

TermDefinition
Static Electricity Static electricity is the accumulation of excess electric charge on an object.
Law of conservation of charge The law of conservation of charge states that charge can be transferred from object to object, but it cannot be created or destroyed.
Electric field An electric field surrounds every electric charge and exerts the force that causes other electric charges to be attracted or repelled.
Conductor A conductor is a material through which electrons move easily.
Insulator An insulator is a material in which electrons are not able to move easily.
Charging by contact Charging by contact is the process of transferring charge by touching or rubbing.
Charging by induction The rearrangement of electrons on a neutral object caused by a nearby charged object is called charging by induction.
Electroscope An electroscope is a device that can detect electric charge.
Voltage difference A voltage difference is related to the force that causes electric charge to flow, voltage difference is measured in volts (V).
Electric circuit An electric circuit is a closed path that electric current follows.
Resistance Resistance, which is measured in ohms (Ω), is the tendency for a material to resist the flow of electrons and to resist the conversion of electrical energy into other forms of energy, such as thermal energy.
Ohm's law According to ohm's law, the current in a circuit equals the voltage difference divided by the resistance.
Series circuit A series circuit is an electric current with only one branch.
Parallel circuit Parallel circuits contain two or more branches for current.
Electrical power Electrical power is the rate at which electrical energy is converted to another form of energy. The equation for electrical power is: Electrical power (P) (watts)=Current (I) (amperes) x Voltage difference (V) (volts).
