component K
Fig. 10.2
At low temperature, component K has a much greater resistance than resistor R.
At high temperature, component K has a much smaller resistance than resistor R.
State and explain the effect on the lamp when the temperature changes from very low to very
high.
Refer to the voltage at point X in your explanation.
