Antik Ohmmeter
An ohmmeter is an electrical instrument that measures electrical resistance the opposition offered by a substance to the flow of electric current micro ohmmeters microhmmeter or micro ohmmeter make low resistance measurements.
Antik ohmmeter. By adjusting r 2 the meter is adjusted to a full scale current. In the simplest ohmmeters the resistance to be measured may be connected to the instrument in parallel or in series. Most multimeters have a fuse to help protect against misuse.
Een ohmmeter is een elektronisch apparaat waarmee je de weerstand kunt meten in een elektronisch component of circuit. The series type ohmmeter consists of a current limiting resistor r 1 zero adjusting resistor r 2 emf source e internal resistance of d arsonval movement r m and the resistance to be measured r.
