A material through which an electron does not easily flow. Two objects will attract each other when… One example of a good conductor is … An electric field gets stronger as you … An equal number of protons and electrons What is an insulator? When they have opposite charges? What is copper? What is get closer to a charge? An example of a good conductor is … The steady flow of electrons through a conductor is …. When the resistance in an electric circuit increases, the current flowing in the circuit ….. A circuit that has two or more paths for electrons to follow is a ….. A continuously flowing closed loop is a… What is copper? What is electric current? What is decreases? What is parallel circuit? What is a circuit? A circuit that has only one path for the current to follow. The build up of static charge on a object How much electric energy is in an object Which of the following is a device designed to open an overloaded circuit and prevent overheating? a. Circuit breaker b. Conductor c. Resistor d. insulator The rate at which an electrical device converts energy from one form to another is called…. What is a series circuit? What is static charge? What is voltage? What is a circuit breaker? What is electrical power? Heat from the sun moves through space by the process of ….? An example of a longitudinal wave is a _________ wave. Classrooms with carpet are quieter than classrooms with tile because the sound waves are __________. Gravity on the moon is th the gravity felt on about 1/6 earth, this is because…? The distance from the rest line to the crest is called ...? What is radiation? What is a sound wave? What is absorbed? The moon is much less massive that the earth. What is the amplitude? Electric companies usually sell electrical energy in units of… a. Watts b. Amperes c. Volts d. Kilowatt-hours These kinds of circuits are less expensive to make and have one path or branch Homes are usually wired with these kinds of circuits and why? Can objects be charged by moving protons from one object to another? Explain how grounding can offer protection from electric disharges. What is kilo-watt hours? What is a series circuit? Parallel circuits because if one circuit goes out the rest of the circuits will keep working No, proton are held tightly with neutrons in the nucleus of an atom. Grounding causes excess charge to drain into the earth which can absorb the excess . charge
