specified resistance 예문

• Additionally, PWM ( pulse-width modulation ) anemometers are also used, wherein the velocity is inferred by the time length of a repeating pulse of current that brings the wire up to a specified resistance and then stops until a threshold " floor " is reached, at which time the pulse is sent again.
• :Standards might be determined in world-class physics labs, such as the work of Maxwell and Thompson in the 1860's with standard cells and carefully managed galvanometers, or Lord Rayleigh and ( his faithful companion Mrs . Sidgwick ) to define a column of mercury of some length of some cross section at some temperature as having a specified resistance.
