ohm meter in Science
ohmmeter
  (ōm'mē'tər)   
An instrument used for direct measurement of the electrical resistance of a material or electronic component, usually in ohms. Ohmmeters typically use an ammeter to measure current through the material after it has been given some set voltage by the ohmmeter; the direct-current resistance of the sample can then be directly determined through Ohm's law. Compare voltmeter.

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. If in series (series ohmmeter), current will decrease as resistance rises. Ratio meters measure the ratio of the voltage across the resistance to the current flowing through it. For high resistances, the scale is usually graduated in megohms (106 ohms), and the instrument is called a megohmmeter, or "megger."
