Copper
Iron
Silver
Nichrome
Answer is Right!
Answer is Wrong!
The correct answer is D. Nichrome.
Nichrome is a nickel-chromium alloy that is commonly used in electric heater coils because it has a high resistance to heat and electricity. It is also relatively inexpensive and easy to work with.
Copper is a good conductor of electricity, but it is not as resistant to heat as nichrome. Iron is also a good conductor of electricity, but it is not as resistant to heat as nichrome or copper. Silver is the best conductor of electricity, but it is also the most expensive. It is not commonly used in electric heater coils because it is not as resistant to heat as nichrome.
