Background

Weak electrical engineering is a category of electrical power applications. Electric power applications can be classified into strong electricity and weak electricity according to the strength of electric power transmission power. The electricity for buildings and building groups generally refers to weak electricity with alternating current of below 220V50 Hz. The test pencil is also called a test pencil, which is called a 'test pencil' for short. The testing tool is an electrician tool and is used for testing whether the electric wire is electrified or not. The pen body is provided with a neon bulb, and if the neon bulb shines during testing, the neon bulb indicates that the lead is electrified or is a fire wire of a passage. The pen point and the pen tail of the test pencil are made of metal materials, and the pen holder is made of insulating materials. When the test pencil is used, a user must touch a metal part at the tail end of the test pencil by hand, otherwise, because a charged body, the test pencil, a human body and the ground do not form a loop, neon bulbs in the test pencil cannot emit light to cause misjudgment, the charged body is considered to be uncharged, and the test pencil is one of tools frequently used by electricians and used for judging whether an object is charged. Its internal structure is a bulb with only two electrodes, in which the interior of said bulb is filled with neon gas, commonly called neon bulb, its one pole is connected to pen point, and its another pole is series-connected with a high-resistance, and then connected to another end of pen. When the voltage between two poles of neon bulb reaches a certain value, glow is produced between two poles, and the intensity of glow is in direct proportion to the voltage between two poles. When the voltage of the electrified body to earth is larger than the initial glow voltage of the neon bulb and the tip of the test pencil is contacted with the electrified body, the other end of the test pencil is grounded through a human body, so that the test pencil can emit light. The resistor in the test pencil is used for limiting the current flowing through the human body so as to avoid danger.
