Gold leaf electroscope
A gold leaf electroscope
A gold leaf electroscope is a simple device used to detect the presence and magnitude of electric charge. It consists of a metal rod or plate (usually brass) with a pair of thin gold leaves attached at the top. The rod is usually housed in a glass container to protect it from air currents.
Here’s how it works:
- Charging: When a charged object is brought close to the metal rod or plate, the electric charge induces a redistribution of charge in the metal rod. If the charged object is positively charged, it repels positive charges in the metal rod to the leaves, causing them to acquire a positive charge and repel each other. Similarly, if the charged object is negatively charged, it induces a negative charge in the metal rod, causing the leaves to acquire a negative charge and repel each other.
- Detection: The repulsion between the leaves causes them to diverge away from each other. The degree of divergence depends on the magnitude of the electric charge present. A stronger charge will cause the leaves to diverge further.
- Neutralization: If the charged object is removed, the leaves may remain diverged for some time if the electroscope is insulated from its surroundings. However, over time, any charge present on the leaves will dissipate due to the conductivity of the air and the surroundings, causing the leaves to return to their original position.

Knife switch
A knife switch, also known as a switchblade switch or simply a blade switch, is a type of electrical switch characterized by a hinged lever that resembles a knife blade. It’s commonly used in electrical circuits to manually interrupt or connect the flow of current. The blade of the switch is typically made of metal and is connected to a conductive component of the circuit.

Conversely, moving the blade to the other side breaks the connection, interrupting the flow of electricity. Knife switches were once commonly used in electrical systems, but they have largely been replaced by more modern switches in most applications. However, they still hold significance in certain contexts, such as educational demonstrations and historical exhibits.

Voltmeter 30v electric and dual range
A voltmeter is an instrument used to measure voltage in electrical circuits. A voltmeter with a 30V electric dual range is versatile for laboratory use. It means it can measure voltage up to 30 volts, and it likely has multiple measurement ranges within that 30-volt range for increased accuracy and versatility.
The “dual range” feature typically means that the voltmeter has two separate measurement ranges. For instance, it might have a lower range (e.g., 0-10 volts) and a higher range (e.g., 0-30 volts). This allows you to select the appropriate range for the voltage you’re measuring, ensuring that the instrument provides accurate readings.
In a laboratory setting, having a voltmeter with dual range capabilities can be beneficial because it allows for more precise measurements across a wider range of voltages, accommodating various experimental setups and electrical components.
