deflection tube的意思|示意

Deflection tubes are used to measure the potential difference between two points in a circuit. The device is made up of two hollow tubes joined together horizontally. There is an opening at the bottom of each tube, and the tubes are filled with mercury or some other liquid that can conduct electricity. An electric current is applied to the circuit, causing the liquid to flow through the tubes. As the liquid flows, it deflects away from the opening in the lower tube, allowing a measurement to be taken.

Deflection tubes are useful in areas such as electrical engineering, electronic engineering, and physics, as they allow researchers to measure the potential difference between two points in a circuit. The device is also beneficial to industry, as it can be used to measure the current running through a wire. By understanding how the current changes over time, technicians can adjust devices and ensure that the circuit is functioning correctly.

Deflection tubes are simple to operate and can be used with any voltage or current. To measure the potential difference, the technician will connect the device to the circuit and apply a voltage or current. The liquid will flow through the tubes, and the technician will measure the deflection of the liquid to determine the potential difference.

Deflection tubes have a number of advantages. They are relatively inexpensive, easy to use and require minimal maintenance. In addition, they can be used to measure weak signals and can detect small changes in potential difference. As a result, they are an essential tool for electrical engineers and technicians.
