Name the alloy which is used to make the heating elements of electrical heating appliances like an electric iron.

Options

A. Copper
B. Nichrome
C. Tungsten
D. Zinc

Answer

**Step-by-Step Solution:**

1. **Identify the Purpose**: The question asks for the alloy used in heating elements of electrical appliances, specifically an electric iron.

2. **Understanding Heating Elements**: Heating elements are components that convert electrical energy into heat energy. They need to have certain properties, such as high resistance, to generate heat effectively when an electric current passes through them.

3. **Know Common Alloys Used**: Among various alloys, one that is commonly known for its use in heating elements is an alloy made from nickel and chromium.

4. **Name the Alloy**: The specific alloy made from nickel and chromium is called "nichrome."

5. **Explain Why Nichrome is Used**: Nichrome is preferred for heating elements because it has a high electrical resistance, which allows it to produce a significant amount of heat when an electric current flows through it. This heat is utilized in appliances like electric irons to iron clothes.

6. **Final Answer**: Therefore, the alloy used to make the heating elements of electrical heating appliances like an electric iron is **nichrome**.
