Question | Answer |
electricity | a form of energy caused by moving electrons |
protons | carry a positive charge |
electrons | carry a negative charge |
ion | an atom with a positive or negative charge |
The Law of electric charges | like charges repel and opposite charges attract |
static charge | the buildup of electrons on an object |
electric discharge | the rapid movement of excess charge from one place to another |
electric current | a flow of electrons through a conductor |
electric circuit | a close conducting loop through electric currents continuously flow. |
series circuit | a circuit that has only one path for the electric currents to flow |
parallel circuit | a circuit that has more than one path for the electric current to flow |
conductor | a material that allows electrons to move through easy |
Insulator | a material in which electrons cannot move easily from place to place |
voltage | the measure of how electric energy an electron in a circuit can gain from a circuit |
what is voltage measured in | volts |
battery | a series of electrochemical cells connected together |
electrolyte | a substance that dissolves in water to form a conducting solution |
direct current | a current that only flows in one direction |
oxidation | the electric field forces the electrons to leave the negative terminal to move towards the positive battery terminal |
ampere | a measure of the number of electrons flowing in a circuit in a given amount of time |
resistance | opposes the flow of electrons in a circuit |
4 factors that effect resistance | length, width, material, and temperature |
Ohms law | current in a wire is equal to the voltage divided by the resistance |
