Core Practical: Investigating Charging by Friction
Nov 2, 2024 · Core practical 3: investigating charging by friction Aim of the experiment. The aim of this experiment is to investigate how insulating materials can be charged by friction. Variables. Independent variable = Rods of different material. Dependent variable = Charge on the rod. Control variables: Time spent rubbing the rod. Using the same type of ...
Rubbing two different materials together, a process known as charging by friction (AKA charging by rubbing), is the simplest way to give something a charge. This is what you do every time you drag your feet along a carpet so you can reach out and zap someone's ear. Your feet in socks and the carpet are doing charging by friction.
Michael Faraday used a metal ice pail as a conducting object to study how charges distributed themselves when a charged object was brought inside the pail. Suppose we lower a positively charged metal ball into the pail without touching it to the pail.

To demonstrate charging by friction, suspend two inflated balloons using long nylon threads. The balloons must be well above the table or floor, and far from any metal supports. Charge the balloons with like charges by rubbing each in turn against a woollen garment or cloth. Stand well away and let students see the effect of like charges repelling.
You will demonstrate all three of these phenomena—charging by induction, charging by contact, and electrostatic shielding—in this experiment. We explain these phenomena in more detail in what follows.
