This may be the measured resistance caused by measuring while the resistor is chargednegative image, need to disconnect the resistor from the circuitnegative image, that is, you cannot measure online. At this time, there is a weak voltage between the red and black probesnegative imageWhen measuring the resistance, the current from the red probe flows to the black probe. After calculating the current, the digital multimeter displays the resistance value. The normal display is equal to or greater than 0. When measuring online live, there is a voltage at both ends of the resistor. When the probe is placed on both ends of the resistor, it will change the value of the original circuit.
1 Water absorbing elephants Place the elephant by the window to ensure that the elephant's trunk points to the water source. For example, if there is no water source in swimming pools, ponds, and the sea, you can choose to face the elephant towards the square avenue or low-lying area to absorb wealth and enhance wealth. 2 Gathering wealth elephants This kind of elephant shape is common. Carrying the elephant's trunk with its mouth open and exposed teeth can be placed at home. It can make up for the financial shortcomings of modern buildings, enhance the strength of the mountain, and enhance the luck of noble people and careers. 3 Water spraying elephants.
Which quadrant is positive and negative in the planar rectangular coordinate system, the second quadrant and the fourth quadrant are negative positive quadrants, that is, their abscissa and ordinate symbols are different, and one is negative. The first quadrant and the third quadrant are positive or negative quadrants, that is, the coordinate symbols on the two coordinate axes are the same. The following is the following: 1 The four quadrants in the planar rectangular coordinate system are divided according to the symbols of the abscissa and ordinate. Each quadrant has a specific coordinate symbol combination 2 of the second quadrant.
In men's hearts, women should be gentle and kind, no matter what happens.negative imageWhen anything happens, a woman should use a virtuous way to handle the matter between two people. However, when a woman is particularly angry and in extreme pain, she will also be in her heart, especially unable to let go. When she is very desperate and painful, she will also think of using some cruel behaviors to express her unhappiness in her heart. But when a woman's behavior is too ruthless.
There are many reasons for the formation of negative pressure, mainly involving fluid dynamics, thermodynamics and specific situations in engineering applications. Detailed explanation 1 Fluid dynamics perspective In fluid mechanics, negative pressure usually refers to the pressure in a certain space or area lower than the pressure of the surrounding environment. When gas or liquid flows, if the flow rate at the outlet is greater than the flow rate at the inlet, then a negative pressure area will be formed inside the system. This is due to the outflow of fluid.
The negative image of various characters The negative characters refer to the characters who are opposed to the positive characters, the protagonists or moral characters in literary and artistic works such as stories, novels, movies and other works. They usually have negative personality characteristics and behaviors, such as evil, cunning and callous, etc. The following are several common types of negative characters. 1 Evil forces represent such negative characters who usually have extremely bad behaviors and bad motives. They may be.
Negative numbers in debit accounts are relatively rare, which usually means that a large-scale red-letter write-off of main business costs has occurred. If main business costs are often negative, this may attract the attention of the tax department. In the accounting field, debit accounts are used to record asset increases or liability reductions. The corresponding concept is that credit accounts take highway design as an example. When excavation has been completed but filling has not yet been completed, it is necessary to borrow or purchase soil from the borrowing ground. If filling and excavation is deployed, The amount of soil required for filling does not meet the requirements, and soil needs to be collected from the borrowing ground or purchased from other places to fill it.
The phenomenon of the ammeter showing a negative number mainly involves two situations. First, when the current flow direction is opposite to the positive direction of the ammeter, the ammeter will show a negative value. This phenomenon is common in DC circuits. When the current flows in from the positive pole and flows out from the negative pole, it means that the current flow direction is opposite to the positive direction of the ammeter, so the ammeter displays a negative value. Secondly, when the current direction continues to change in the circuit, the ammeter may have alternating positive and negative values. This situation is common.
