Term
 Kilohm
Definition
 100 ohms
Term
 Megohm
Definition
 1,000,000 ohms
Term
 insulator
Definition
 a material that has a very high resistance to elecricity
Term
 conductor
Definition
 a material with a low resistance to electricity
Term
 the omega symbol is used to represent what?
Definition
 ohms
Term
Definition
 electrical resistance decreases
Term
 Who discovered the ohm
Definition
 George Simon Ohm
Term
 The resistance is proportional to
Definition
 the distance
Term
 electrolyte
Definition
 conductive fluid
Term
 volts(voltage)
Definition
 measure of electrical pressure(measured in volts)
Term
 To measure resistance, a red wires attaches to __ while a black wire attaches to __
Definition
 volts; common
Term
 amperage(amps)
Definition
 electrical flow per second
Term
 fuse
Definition
 a part that melts to protect the rest of the circuit(if it breaks then the circuit stops)
Term
 millivolt
Definition
 1/1000 of a volt
Term
 milliamperes(milliamps)
Definition
 1/1000 of an ampere
Term
 Who invented the battery
Definition
 Alessandro Volta
Term
 DC Current/Direct Current
Definition
 current that flows in one direction
Term
 AC/Alternating Current
Definition
 current that switches from positive to negative(usually 60 times each)
Term
 Who discovered amperes
Definition
 Andre Marie Ampere
Term
 Resistors
Definition
 components to resist electricity
Term
 potentiometer
Definition
 turns resistance up and down(works by rubbing a conductor against the conductive or plastic wire)(the resistance)
Term
 you test a potentiometer by
Definition
 using a multi-meter on ohm setting
Term
 If one adds the voltage drops across the devices in the circuit
Definition
 the total is the same as the voltage supplied by the batteries
Term
 you measure the voltage directly between
Definition
 two points in a circuit
Term
 you can only measure your current when it
Definition
Term
 How does one measure the flow of their circuit
Definition
 set your meter to milliamperes and measure (too much WILL blow your circuit)
Term
 a higher resistance limits what?
Definition
 the flow of current amperage
Term
 Resistors in a series are oriented so that one
Definition
 follows the other
Term
 Resistors in parallel are also oriented
Definition
 side-by-side
Term
 When you put two equal valued resistors in series you
Definition
 double the total resistance, because electricity has to pass through both barriers in succession
Term
 When you put two equal-valued resistors in parallel you
Definition
 divide the resistance by two, because you're giving electricity two paths which it can take instead of one
Term
 in parallel
Definition
 when a circuit splits into two different paths, each with the same circuit part and then merges again into the original circuit.
Term
 in series
Definition
 when two or more circuit parts are connected in the same direction, in the same circuit, without spliting up
Term
 inductance
Definition
 the ability to induce magnetic effects
Term
 On a multimeter any number with a "V" after it (e.g. 2V, 20V, 500V etc) means
Definition
 No higher than 2 volts, 20 volts, 500 volts, etc
