    • use the keywords non-linear and linear when discribing components in a iv graph
    • LDR's in bright light, resistance falls but in darkness, the resistance increases
    • in thermistors- temperature dependant resistors, in hot conditions the resistance will drop and in cool conditions the resistance will increase
    • LDR's are useful in automatic night lights and burglar alarms whilst
    • thermistors are useful in temperature detectors like car engine temperature sensors and thermostats
