What happens to the resistance when the length of the conductor is doubled without affecting the thickness of the conductor?
What happens to the resistance when the length of the conductor is doubled without affecting the thickness of the conductor? what happens to the resistance when length of conductor is doubled without affecting the thickness of conductor? R = ρl/A. According to this relation, resistance is directly proportional to length of the conductor. Hence, when […]

Why does a paperclip sink in soapy water?
Why does a paperclip sink in soapy water? When you initially drop the paper clip into the bowl of water, it sinks, as the paperclip is too dense. Adding the dish soap breaks the bonds between the water molecules, thus breaking the surface tension and causing the paper clip to sink. Does a paperclip sink? […]
