On heating, the resistance of a semiconductor :
aIncreases
bDecreases✓ Correct
cRemains same
dfirst increases and then decreases
eNone of the above / More than one of the above
Explanation
Semiconductors are solid substances whose resistivity is greater than that of conductors but less than that of insulators. The resistance of a semiconductor decreases when temperature increases.
