Mica is used in electrical appliances such as electric iron because mica is A. a good conductor of heat but a bad conductor of electricity B. a bad conductor of heat but a good conductor of electricity C. a good conductor of heat as well as electricity D. a bad conductor of heat as well as electricity

Mica is used in electrical appliances such as electric iron because mica is a good conductor of heat but a bad conductor of electricity.

Mica is a mineral that is composed of sheets of silicate that are bonded together. These sheets are very thin and can be easily separated. Mica is a good conductor of heat, but a bad conductor of electricity. This makes it ideal for use in electrical appliances, where it can be used to insulate wires and other components.

Mica is also used in other applications, such as roofing, windows, and insulation. It is a versatile material that has many uses.

Here is a brief explanation of each option:

• Option A: Mica is a good conductor of heat but a bad conductor of electricity. This is the correct answer.
• Option B: Mica is a bad conductor of heat but a good conductor of electricity. This is not the correct answer. Mica is a good conductor of heat, but a bad conductor of electricity.
• Option C: Mica is a good conductor of heat as well as electricity. This is not the correct answer. Mica is a good conductor of heat, but a bad conductor of electricity.
• Option D: Mica is a bad conductor of heat as well as electricity. This is not the correct answer. Mica is a good conductor of heat, but a bad conductor of electricity.
