Answer: Nichrome.
- A Copper
- B Silver
- C Nichrome
- D Aluminum
Correct answer: C. Nichrome
Explanation: Nichrome (nickel-chromium alloy) has high resistivity and high melting point: ideal for heating elements.
In series, the same current flows through both resistors; in parallel, the current splits between branches and the voltage across each resistor is the same.
