In the year 1600, British physician William Gilbert invented the first electroscope with a pivoted needle called versorium. Electroscope detects the charge based on the Coulomb electrostatic force which causes the motion of test charge

The electroscope is an early scientific instrument used to detect the presence of electric charge on a body. It detects charge by the movement of a test object due to the Coulomb electrostatic force on it. The amount of charge on an object is proportional to its voltage.The accumulation of enough charge to detect with an electroscope requires hundreds or thousands of volts, so electroscopes. Widely used in the pharmaceutical industry, mass spectrometers can help chemists design new drugs much more quickly; among other things, they're useful for figuring out how to maintain the level of a chemical in the body for a certain period of time (which is the key to designing drugs that work effectively) thermometer. A thermometer is an instrument that measures temperature. It can measure the temperature of a solid such as food, a liquid such as water, or a gas such as air.

An electroscope is a simple instrument to detect the presence of electric charge. The old electroscopes consisted of a box or cylinder with a front glass wall so the experimenter could look inside, and an insulating top through which a conducting rod with a ball or disk (called an electrode) on top entered the box Such an experiment, called the flame test, has been used in conjunction with other tests in many qualitative analysis schemes for metal ions. Whatever color our eye perceives indicates what metal ion is present. When more than one metal ion is present, viewing the flame through a colored glass filter can help mask any interference

Electric charge Definition. Electric charge is defined as: An electrical property of matter that exists because of access or a deficiency of electrons.There are two types of electric charges, positive charges, and negative charges. Like charges repel each other while unlike charges attract each other. SI Unit of Electric charge is Coulomb Hi-Res Mode: Like peak detect, hi-res mode is a way of getting more information in cases when the ADC can sample faster than the time base setting requires. In this case, multiple samples taken within one waveform interval are averaged together to produce one waveform point. The result is a decrease in noise and an improvement in resolution for low-speed signals Energy, a measure of the ability to do work, comes in many forms and can transform from one type to another. Examples of stored or potential energy include batteries and water behind a dam. Objects in motion are examples of kinetic energy. Charged particles—such as electrons and protons—create electromagnetic fields when they move, and these fields transport the type of energy we call.

Remote-sensing instruments record characteristics of objects at a distance, sometimes forming an image by gathering, focusing, and recording reflected light from the Sun, or reflected radio waves emitted by the spacecraft. When an instrument provides the illumination, as does radar, it is referred to as an active remote-sensing instrument These systems can be made small enough to be used in hand-held devices or wearable night-vision goggles.

Cells can achieve this charge separation by allowing charged ions to flow in and out through the membrane. The flow of charges across the cell membrane is what generates electrical currents. Cells control the flow of specific charged elements across the membrane with proteins that sit on the cell surface and create an opening for certain ions. Charge is a physical property of matter, just like mass or volume. Charged objects experience a force when placed in an electric field. There are 2 types of charge, positive and negative. Like charges repel and unlike charges attract (Fig. 1). Charge is detected when 1 charged object exerts a force on another object Cocaine is a tropane alkaloid with central nervous systems (CNS) stimulating and local anesthetic activity. Cocaine binds to the dopamine, serotonin, and norepinephrine transport proteins and inhibits the re-uptake of dopamine, serotonin, and norepinephrine into pre-synaptic neurons. This leads to an accumulation of the respective neurotransmitters in the synaptic cleft and may result in.
