Definition of megohm in English:

megohm

noun ˈmɛɡəʊmˈmeɡōm

A unit of electrical resistance equal to one million ohms.
兆欧（姆）（电阻单位，等于100万欧姆）
Example sentencesExamples
- His third prototype culminated his design, which, he wrote, is ‘a simple switching gate circuit which produces an AC current; the cycle rate is achieved by the use of two one megohm resistors and a 0.01 microfarad capacitor.’
- With this megohm meter all you need to do is connect both leads to your motor or device and press and hold the button and view the graph.
- After drying for 24 hours at ambient temperature, its surface resistivity is 0.005 megohm per square, a value which is 1000 times less than the minimum of 5 megohms per square required.
- This inaccurate value is 6.67% higher than the actual parallel resistance of 25 megohms.
- The tester compares the measurement to preset lower and upper (1.25 or 10 megohms) resistance levels.

Origin

Mid 19th century: from mega- (as a unit of measurement) + ohm.
