Brand Name:icchipcn.com
Condition:New
Type:Logic ICs
Purpose:
1. Observe the phenomenon that the high-voltage electrode breaks through the air and forms an arc.
2. Understand the reason for the rise of the arc.
experiment equipment:
Jacob's Ladder
submit questions:
After the high voltage is generated by the high voltage generator, the commercial power is applied to a pair of electrodes with a narrow bottom and a wide top and a claw-shaped top. in two electricity
Sparks started very recently and moved upwards. Why does this phenomenon occur after the arc moved to the upper end disappears
Woolen cloth?
Conjectures and assumptions:
1. The high voltage between the electrodes breaks down the air to generate an arc.
2. The arc is first generated at the closest point between the two electrodes.
experiment procedure:
1. Press and hold the switch for 5 seconds, and observe the movement characteristics of the arc.
(You can press it again after 5 seconds of rest, keep your hands away from the electrodes, pay attention to safety. Do not press for a long time, too much ozone will pollute the air in the laboratory)
2. Pay attention to the location where the arc starts and ends.
Explore questions:
1. Explore the high voltage between the electrodes to break down the air to generate an arc.
2. Observe the position of arc generation and extinction.
3. Explore why the arc keeps rising?
Extracurricular Activities:
Find out about the miles of electric current that can be generated by a single lightning bolt.
Precautions:
When the instrument is working, a high voltage will be generated on the electrodes. Pay attention to safety and operate under the guidance of the teacher. The experiment should not exceed 5 consecutive times, and the experiment interval should be longer than 5 minutes.
