Current correct answersRate of flow of charge Coulomb correct answersThe amount of charge passing a point when a current of 1A flows for 1s Potential difference correct answersThe work done per unit charge in moving a small point positive charge between two points Threshold Voltage for a Diode correct answersThe voltage at which a current will begin to flow at, assumed to be +0.6V if not stated Reverse Bias correct answersWhen very little currency can flow in the reverse direction of a diode Variable Resistor correct answersCan be used to change the current through a circuit can also be called a rheostat NTC Thermistor correct answers(A type of semiconductor) that has decreasing resistance when its temperature increases - negative temperature coefficient Transitional Temperature correct answersThe critical temperature at and below which a superconductor has zero resistivity Semiconductor correct answersA group of materials which conduct electricity (not as well as metals), when their temperature rises they can release more charge carriers and their resistance decreases Resistance correct answersThe ratio of a components potential difference to its current Volt correct answersThe potential difference across a component when 1 joule of energy is used to move a coulomb of charge through a component Ohm's Law correct answersProvided that the physical conditions remain the same, the current through an ohmic conductor is directly proportional to the potential difference across it Ohmic conductor correct answersA material that follows Ohm's law when physical components remain the same Diodes correct answersComponents made from semi conductors that only allow current to flow in one direction
