How can you tell if metal leaf electroscope is neutral or positive?
you cant
What type of instrument can detect the presence of an electrical charge?
a gold leaf electroscope. if initially charged negatively, the deflection of the leaf with respect to the electroscope is increased if a negatively charged object approaches the electroscope. conversely if a positively charged object approaches, the deflection is reduced. the angle of deflection is proportional to the magnitude of the charge.
Name the kind of electroscope that can recognized to be charged just by observation?
Type your answer here... electroscope switch electroscope square
What does an electroscopic measure?
An electroscope is an early scientific instrument that is used to detect the presence and magnitude of electric charge on a body. It was the first electrical measuring instrument. The first electroscope, a pivoted needle called the versorium, was invented by British physician William Gilbert around 1600.[1] The pith-ball electroscope and the gold-leaf electroscope are two classical types of electroscope that are still used in physics education to demonstrate the principles of electrostatics. A type of electroscope is also used in the quartz fiber radiation dosimeter.Electroscopes detect electric charge by the motion of a test object due to the Coulomb electrostatic force. The electric potential or voltage of an object equals its charge divided by its capacitance, so electroscopes can be regarded as crude voltmeters. The accumulation of enough charge to detect with an electroscope requires hundreds or thousands of volts, so electroscopes are only used with high voltage sources such as static electricity and electrostatic machines. Electroscopes generally give only a rough, qualitative indication of the magnitude of the charge; an instrument that measures charge quantitatively is called an electrometer.Source : Wikipedia
What if the electroscope leaves hang down?
they are not charged
What are the kind of electroscope?
metal-leaf and pith-ball
Uses of an electroscope?
An electroscope can be used to determine the charge of an object.
How can you tell if metal leaf electroscope is neutral or positive?
you cant
What is the instrument that is used to detect static charge?
An electroscope is an instrument used to detect static electricity.
What kind of charge is induced on a metal-leaf electroscope by an ebonite rod?
Static
Why do the leaves of an electroscope spead apart when a charged object touches the metal knob?
The charged object charges both leaves of the electroscope with like charges and like charges repel.
What is an instrament used to detect charges?
Electroscope
Principle of electroscope and types of electroscope?
Like charges repel and unlike charges attract each other this is the fundamental principle used in an electroscope to detect presence and amount of charge. There are mainly 2 tpes of electroscopes pith ball electroscope and gold leaf electroscope
What device is used for testing the charge of an object?
An Electroscope.
What device is used to see if something is charged?
electroscope
How can an electroscope be used to determine what charge a body has?
hitler?
What would change about the way an electroscope worked if its metal knob was replaced with a plastic one?
you would adapt one.
