Ohm, английский
- A unit of electrical resistance.
- The unit of resistance. the electrical resistance between two points of a conductor where
- The unit of resistance. the electrical resistance between two points of a conductor where a constant difference of potential of 1 v applied between these points produces in the conductor a current of 1 a, the conductor not being the source of any electromotive force. oscilloscope (also cro, from cathode ray oscilloscope)an electronic device that can measure the signal changes versus time. a must for any cctv technician.
- The unit of electrical resistance of a conductor such that a constant current of 1 ampere in it produces a decrease in voltage across it of 1 volt. ohm’s law a law stating that the current in an electric circuit is directly proportional to the electromotive force (voltage) in the circuit and inversely proportional to the resistance in the circuit. ohs on drawings, abbr. for “oval-headed screw.”
- Ом
- A measure of the electrical resistance of a material equal to the resistance of a circuit in which the potential difference of 1 volt produces a current of 1 ampere.
- The unit of measurement of electrical resistance. symbol is ??. a resistance of one ohm will allow one amp of current to pass through it at a voltage drop of one volt. ohm’s law: a simple mathematical formula that allows either voltage, current or resistance to be calculated when the other two values are known.
- A measure of the electrical resistance of a material equal to the resistance of a circuit
- The ohm is the unit of electrical resistance. it is the value of a resistance that will pass one ampere of current at a potential of one volt.
