| 21. | The SI unit of electrical resistance, named after Georg Simon Ohm.
|
| 22. | Values ranged from fractions of an ohm to 22 megohms.
|
| 23. | The above equation is the modern form of Ohm's law.
|
| 24. | This reformulation of Ohm's law is due to Gustav Kirchhoff.
|
| 25. | A hydraulic analogy is sometimes used to describe Ohm's law.
|
| 26. | Video cables are 75 ohm impedance, low in capacitance.
|
| 27. | Similar examples of dimensionally equivalent units include ohm per square.
|
| 28. | The particular crystal exhibited a real resistance of 114 ohms at resonance.
|
| 29. | This is the equivalent of 5 microvolts in 50 ohms.
|
| 30. | The device will no longer follow Ohm's law.
