Resistor theory
WebThermistors and LDRs. You should be able to recognise the circuit symbols for a thermistor and an LDR (light-dependent resistor), and know how the resistance. of these … Webenough to handle the largequantities of current remaining would have to have resistor grids of tremendous cross section or many parallel grid paths, and as a result would be very expensive. On the other hand, if extreme limitation of ground current by resistors is desired, the resistor again becomes excessively expensive.
