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 |
