Power; Thermistors and LDRs; Current-voltage graphs. ... Take a graph where the current flow is shown on the vertical axis and the voltage is shown on the horizontal axis.

His data table and the resulting graph of current versus temperature are works of art, and they allowed him to make sensible component selections for a fixed 250-mA current limit with a reasonably ...
