An ohmmeter is an electrical instrument that measures electrical resistance (the opposition offered by a circuit or component to the flow of electric current). Multi-meters also function as ohmmeters when in resistance-measuring mode. An ohmmeter applies current to the circuit or component whose resistance is to be measured.

Un ohmmètre est un instrument de mesure qui permet de mesurer la résistance électrique d'un composant ou d'un circuit électrique. L'unité de mesure est l' ohm, dont le symbole est Ω. Deux méthodes peuvent être utilisées pour mesurer la valeur d'une résistance :

ohmmeter, instrument for measuring electrical resistance, which is expressed in ohms. In the simplest ohmmeters, the resistance to be measured may be connected to the instrument in parallel or in series. If in parallel (parallel ohmmeter), the instrument will draw more current as resistance increases.

Dec 23, 2024 · An ohmmeter is an electronic device that measures resistance in an electronic component or circuit. It works by using 2 probes to send a current through the circuit and measuring how much resistance, in ohms (Ω), that current encounters.

Jul 30, 2020 · What is an Ohmmeter? An ohmmeter is an electrical instrument used to measure the resistance in a circuit or a component. The opposition to the flow of electric current is a measure of resistance in the electrical circuit. The unit of electrical resistance is ohms (Ω).

Feb 24, 2012 · An ohmmeter (also known as an ohm meter) is an instrument that measures the electrical resistance of a material (resistance is a measure of the opposition to the flow of electric current).

Definition: The meter which measures the resistance and the continuity of the electrical circuit and their components such type of meter is known as the ohmmeter. It measures the resistance in ohms. The micro-ohmmeter is used for measuring the l ow resistance and the mega ohmmeter measures the high resistance of the circuit.

Apr 11, 2023 · Ohmmeter is used to directly measure resistance of a device, element, circuit or any portion thereof. This meter is used to determine approximate (not too accurate) resistance of the circuit components.

Jul 16, 2021 · In this topic, you study the definition, working & diagram of Ohmmeter. This is a portable instrument, which indicates the value of a resistance (in ohm. Kiloohm or Megaohm) directly by the deflection of a pointer on a scale (Fig. 1). Fig. 1: Ohmmeter.

An ohmmeter can be defined as, it is one kind of electronic device mainly used for calculating electrical resistance of a circuit, and the unit of resistance is ohm. Electrical resistance is a calculation of how much an object resists allowing the flow of current through it.
