Description
- Import of our company
- Complies with the curriculum
- There are 2 items in the set
- Product dimensions: 142mm x 88mm x 190mm 350g/pc
- The product is presented in its original foam packaging.
- This instrument shall be used in electrostatic experiments to check whether the object is charged, the positive or negative charges of charged objects, the insulation of objects, demonstrate induction charging and so on.
- Foil electroscope structure: This instrument consists of outer casing, round sphere or disc, conducting rod, foil and median card.
- Whether the objects are charged shall be checked: Touch the objects to be examined with the top of the electroscope. If the metal foil on the electroscope is folded, the object is charged. If the foil is not folded, the object is not charged.
- Check the positive or negative charges of charged objects.
- Let the metal foil of the electroscope fitted with a known charge (positive or negative charge) firstly to make it fold to a certain angle, and then move the objects to be checked near the top of the electroscope (without touching). If the foil is folded to an increased angle, the charge on the objects is the same as the charge on the electroscope. If the foil folds to a smaller angle, then the charge on the objects is different from the charge on the electroscope.
- The demonstration of conductors and insulators: The two identical electroscopes shall be used with one of them is charged to make sure the metal foil is folded at a certain angle (the larger the angle of the metal foil will be folded with heavier electricity and the better the demonstration effect). The other is uncharged, so the foil will not be folded. Then the insulated handle of the connecting rod shall be held to make sure that the two ends of the metal rod contact the top of the two electroscopes respectively (then it can be seen that the metal foil of the electroscope that was originally uncharged is opened, which indicates that the charge carried by one electroscope is passed through the metal rod to the other electroscope, so that the metal is a conductor. If a glass rod or a hard rubber rod are used to connect the top of the two electroscopes, the folding angle of the live electroscope metal foil will not be changed, and the non-live electroscope metal foil will not be folded, which indicates that charge cannot be transferred through glass rods or hard rubber rods that is to say the glass rods and hard rubber are insulators.
- A kind of very thin tin sheet is used in the electroscope for the foil in order to make the sensitivity high due to transportation and other reasons, the foil may be bent or other situations, so that the loop of the electroscope can be removed, and the cover (glass cover) can be taken off. Be careful when moving the instrument to prevent severe vibration from damaging it.
- You’d better to wipe the metal ball and rod with a soft dry cloth before use the instrument due to insulating property may be damaged to because of the influence the dust and moist. The instruments shall be used after drying in the case of the instrument is in a condition of severe dampness.
- The instrument shall be kept clean and dry after use to keep away from moisture to avoid failure during use.
- To be used in static electricity experiments, it shows whether there is an electric charge on objects, whether the charged charge is positive or negative, the conductivity and insulation conditions produced, etc.
