>Hello Sohib EditorOnline, in this article we will discuss about the working principle of an elektroskop. Elektroskop is a simple apparatus used to detect the presence and magnitude of electric charges. This article will explain in detail how elektroskop works and how it can be utilized in various applications.
What is Elektroskop?
Elektroskop is a device that detects the presence and magnitude of electric charges. It consists of a metal rod or plate connected to a metal disk. The disk is enclosed in a glass container, which prevents dust and other contaminants from interfering with the readings. Elektroskop works by detecting the presence of positive or negative charges on the metal plate, which creates a charge separation between the metal plate and the disk. The resulting electric field can then be measured to determine the magnitude of the charge.
Parts of Elektroskop
An elektroskop usually consists of the following parts:
| Part | Description |
|---|---|
| Metal rod or plate | The part of the elektroskop that is charged by contact with the object being tested. |
| Metal disk | The part of the elektroskop that is used to detect the charge on the metal rod or plate. |
| Glass container | The part of the elektroskop that encloses the metal disk and prevents contaminants from interfering with the readings. |
Types of Elektroskop
There are two main types of elektroskop, the pith ball elektroskop and the gold-leaf elektroskop. The pith ball elektroskop consists of a small ball of pith suspended by a silk thread. When the ball is charged, it will be attracted to any nearby charged object, providing a visual indication of the presence of an electric charge. The gold-leaf elektroskop consists of two strips of gold leaf suspended from a metal rod. When the metal rod is charged, the gold leaf strips will repel each other, providing a visual indication of the presence of an electric charge.
How Elektroskop Works?
Elektroskop works on the principle of electric charge separation. When a positively charged object is brought in contact with the metal plate of the elektroskop, electrons from the plate will flow to the object, leaving the metal plate positively charged. Similarly, when a negatively charged object is brought in contact with the metal plate of the elektroskop, electrons will flow from the object to the plate, leaving the plate negatively charged.
Electric Field
When the metal plate of the elektroskop is charged, it creates an electric field in the surrounding space. The strength of the electric field depends on the magnitude and sign of the charge on the plate. The electric field lines start from the positive charge and terminate at the negative charge, providing a visual representation of the strength and direction of the field.
Charge Induction
When a charged object is brought close to the metal plate of the elektroskop, it can induce a charge separation in the plate. This is known as charge induction. The presence of the charged object creates an electric field in the surrounding space, which polarizes the charges in the plate. This results in a separation of charges, with the side of the plate nearest to the charged object becoming oppositely charged, and the side of the plate farthest from the object becoming similarly charged.
Measurement of Electric Charge
The magnitude of the electric charge on the metal plate of the elektroskop can be measured by observing the deflection of the gold-leaf or pith ball. When a charged object is brought close to the metal plate, the gold-leaf strips or the pith ball will be attracted to the plate, indicating the presence of an electric charge. The degree of deflection can then be used to determine the magnitude of the charge.

FAQ
1. How does elektroskop work?
Elektroskop works on the principle of electric charge separation. When a charged object is brought in contact with the metal plate of the elektroskop, it induces a charge separation in the plate. This creates an electric field in the surrounding space, which can be detected by the gold-leaf or pith ball.
2. What is the purpose of elektroskop?
The purpose of elektroskop is to detect the presence and magnitude of electric charges in various objects, as well as to measure the strength and direction of electric fields.
3. What are the types of elektroskop?
The two main types of elektroskop are the pith ball elektroskop and the gold-leaf elektroskop. The pith ball elektroskop is used to provide a visual indication of the presence of an electric charge, while the gold-leaf elektroskop is used to provide a quantitative measurement of the magnitude of the charge.
