    Important Question with Answer: What is the resistance of an ideal voltmeter?

    The resistance of an ideal voltmeter is infinite. This ensures that it does not draw any current from the circuit, thereby providing an accurate measurement of the potential difference without altering the circuit's conditions.

    Important Question with Answer: Why a detergent powder is mixed with water to wash clothes?

    Detergent powder is mixed with water to lower the surface tension of the water. The reasons for the same are as follows -

    • Better Wetting: Pure water has high surface tension, which causes it to bead up rather than soak into fabric. By reducing this tension, the water can spread more easily and "wet" the clothes more effectively

       

    • Penetration: Lower surface tension allows the water to penetrate the tiny pores and fibers of the cloth to reach trapped dirt and grease.
    • Emulsification: Detergent molecules help bridge the gap between water and oil/grease, allowing the dirt to be lifted away and suspended in the water to be rinsed off.
