The circuit in the figure below is designed to indicate whether the temperature of the thermistor is above or below 
.
The operational amplifier (op-amp) is assumed to be ideal. At , the resistance of the thermistor is 
. On the figure above, draw two light-emitting diodes (LEDs) connected so as to indicate whether the output 
of the op-amp is either 
or 
, label with the letter G the LED that will be emitting light when the temperature is below . Explain your working.
of the thermistor is greater than 
decreases, so 
, therefore the output is positive and hence the LED pointing from
