A heating element in an appliance should not allow current to pass as freely as copper does. Which material from the following is most suitable?
ASilver
BCopper
CNichrome
DAluminium
Answer & Solution
Correct answer: C. Nichrome
Nichrome is a resistor material with comparatively high electrical resistance, so it does not allow current to pass as freely as good conductors such as copper, silver, or aluminium. That makes it suitable where resistance is needed.
