ohm

 (Ω) [ōm]
the SI unit of electrical resistance, named for Georg Simon Ohm; one ohm is produced when a current of 1 ampere flowing through a conductor produces a potential difference of 1 volt. Impedance is also measured in ohms.

Ohm,

Georg Simon, German physicist, 1787-1854.
ohm - the practical unit of electrical resistance.
Ohm law - in an electric current passing through a wire, the intensity of the current in amperes equals the electromotive force in volts divided by the resistance in ohms.

The intracellular action potentials were obtained using glass microelectrodes filled with 3M KCl solution and with a tip resistance of between 10 and 20 megaohms. The signal obtained by the microelectrodes was passed through high input impedance amplifiers, WPI model 750, and an HV Electrometer model 400E.
However, these microphones are characterized with high output resistance (dozen and hundred megaohms) and should be used with a low-ohm microphone cable.
Hyperpolarizing current injections produced graded changes in membrane potential indicating an input resistance of 433 megaohms. Each of the multipolar cells that we recorded from showed similar firing properties.
Specifications of the EMG electrode pre-amplifiers included a common mode rejection ratio of 103 dB, bandwidth of 9 Hz-31 kHz, and an impedance of 100,000 MegaOhms, as reported by the manufacturer.
Specifications include electrical life of 200,000 cycles, operating force of 250 [+ or -] 100 gf, travel of 4.50 [ + or -] 0.2 mm, contact rating of 100 mA @ 12 VDC, contact resistance of 200 milliohms (initial max), insulation resistance of 100 Megaohms (Min.
Deionized water (18.2 megaohms of resistivity) was obtained by MilliQ and Elix systems (Millipore Inc).
