Question

Experiment prove that electricity is a kind of forces​

Answer 1

Answer:

ABSTRACT

The main purpose of this paper is to provide a set of demonstration experiments in electrostatics. Emphasis is put in regard to the making of apparatuses in order to have useful self-made devices from common materials; obviously some apparatuses need special mechanical skill as a turning operation. All devices are designed in order to have a set of portable experiments.

Keywords: demonstration experiments, electrostatics, home-made devices.

Explanation:

1. Introduction

The main purpose of this paper is to provide a set of demonstration experiments in electrostatics. A particular emphasis is put in regard to the making of apparatuses in order to have useful self-made devices from common materials; obviously some apparatus need special mechanical skill as a turning operation. All devices are designed in order to have a set of portable experiments; Author followed the basic philosophy and the tradition of practical physics, as in a celebrated book of the XIX century [1].

 

2. Basic self made apparatuses

The basic apparatuses for a meaningful set of experiments in electrostatics are:

a) generators of charge; spherical insulated conductors; b) Plexiglas rods, PVC conduits for electrical installations, pith (the best light conductor material), very thin fishing line;

c) electroscope.

2.1. Generators of charge

Without an electrostatic machine, some experiments are easily performed with low cost generators of charge. A first source of charge (positive or negative) is a common piezoelectric lighter [2] slightly modified as shown

in Fig. 1. Usually, by pressing the handle, a positive charge is obtained; releasing the handle after touching the ground, a negative charge is obtained. Another generator of charge is a cylindrical version of the Volta's Electrophorus developed through beautiful ideas of D.S. Ainslie [3-5]. Our practical realization is shown in Fig. 2. The apparatus works as a common electrophorus and gives a positive charge being negative the charge on PVC conduit. Our version is developed as portable instrument, but it is obvious that a longer device will give a greater amount of charge. With metal rod (a brass or aluminum tube) an electroscope may be charged by direct contact (or, obviously, by induction). You may charge the can electroscopes by conduction several times in succession.

Answer 2

Answer:

Electricity is a form of energy and it can be converted into any form of energy to create a force.
