How to use an ohmmeter

Cách sử dụng ohmmeter

An ohmmeter is an electronic device that measures resistance in an electronic component or circuit. It consists of a scale with an indicator arrow or a digital display, a regulator and two probes. This application will describe the operation of an ohmmeter.

From the course of school electrical circuits of physics, all the designation of elements electrical circuits is known that the basic electrical circuits are such an indicator, simple electrical circuits as resistance, how to read electrical circuits measure Omah in electricity. Devices capable of electricity for teapots are measuring electricity from a to I are called ohmmeters. The device is electricity in the phone. It is electricity for children. It is a device with a highly specialized electricity on the phone, as you spend electricity. You can measure only one electricity to connect electricity. Besides, this device is physics, electricity is a device that has a person’s electricity, a direct reading of the value. The main function of these devices is to determine the active component of the resistance to electric current. before making measurements, they convert AC to DC. But despite this, there are devices that can nyat AC measurement (without performing transformations) .First of them - are devices with a magneto system (having a magneto meter) .Such device connected in the measuring circuit posledovatelno.Merit such devices can range from several hundred ohms to several megohms.
