| Question | Answer |
| series circuit | a circuit that has one path |
| parallel circuit | a circuit with multiple paths |
| fuse | a device that contains a thin strip of metal that will melt if there is too much current through it |
| power | the rate at which energy is transferred from one form to another |
| ammeter | a device that measure current |
| electrolyte | a substance that conducts electric current in an electrochemical cell |
| induction | the movement of electrons to one part of an object by the electric field of another object |
| conduction | the transfer of electrons from a charged object to another object by direct contact |
| voltage | the difference in electric potential between two places |
| Static is transferred by... | conduction induction friction |
| friction | the transfer of electrons through rubbing |
| What are the four things that affect resistance? | 1. The material the wire is made from. 2. Length (the longer the wire, the higher the resistance) 3. Diameter (thicker=more resistance) 4. Temperature (temperature decreases and resistance decreases) |
| electrodes | the metal rods in the battery (two different types of metals, so one will react faster and differently than the other) |
| What were the components of the first battery? | layers of zinc, paper soaked in salt water, and silver |
| short circuit | a connection that allows the current to take the path of least resistance |
| electrically grounded | A circuit is electrically grounded when charges are able to flow directly from the circuit into Earth. |
| What unit is resistance measured in? | ohms (insert omega symbol here) |
| What is the equation for finding the amount of power? | Power = Voltage x Current P = V x I |
| What is the equation for finding the amount of watts? | Watts = Volts x Amps |
| What are electric current's dangers? | short circuits electric shocks ungrounded wires |
| What is energy's equation? | Energy = Power x Time |
