How would you define gold heat eletroscope?
A gold-leaf electroscope is a device that detects electric charges. It consists of thin gold leaves attached to a conductor that can be charged. When the leaves are charged, they repel each other due to electrostatic forces. This device is commonly used in physics experiments to detect the presence of electric charges.
A device that indicates the presence of an electric current is?
An ammeter is a device that indicates the presence of an electric current by measuring the flow of electric charges through a circuit.
A piezo-electric device generates electricity when?
A piezo-electric device generates electricity when mechanical stress or pressure is applied to it, causing a displacement of positive and negative charges within the material. This displacement of charges creates an electric potential difference, which can be harnessed to generate electricity.
What is a device that can detect the presence of electric charge?
An electroscope is a device that can detect the presence of electric charge. It is typically used to determine whether an object is charged positively or negatively. When an electroscope detects an electric charge, the metal leaves inside the device will either repel or attract each other, indicating the presence of charge.
What device uses chemical energy to give charges electric potential energy?
A battery uses chemical energy to convert it into electrical energy, which then provides charges with electric potential energy. The chemical reactions inside the battery create a flow of electrons, generating an electric potential difference that can power various devices.

Why does light comes on by itself?
One that is controlled by a Photo-Electric device that detects darkness OR One that is controlled by a Clock Timer.
What is under current relays?
A device that disconnects a circuit when ever it detects the electric current is lower than the rated current.

A piezo-electric device generates electricity when mechanical stress or pressure is applied to it, causing a displacement of positive and negative charges within the material. This displacement of charges creates an electric potential difference, which can be harnessed to generate electricity.
What device separates positive and negative charges?
A device that can separate positive and negative charges is a capacitor. Capacitors store electrical energy by storing positive charges on one plate and negative charges on the other plate, creating an electric field between them.

What instrument measures radiation by producing an electric current when it detects a charged particle?
A Geiger-Muller detector is commonly used to measure radiation by producing an electric current when it detects a charged particle. This device contains a gas-filled tube that ionizes when radiation passes through, allowing for the generation of an electric signal that can be measured.
What is olfactory sensing device?
A device that detects odors, such as your nose.
What device creates a potential difference in an electric circuit?
A battery is the device that creates a potential difference in an electric circuit. It establishes an electric field within the circuit that allows charges to move from the positive terminal to the negative terminal, creating an electrical current.
What is the name of the device that detects airplanes in airports?
Radar
