Тезаурус:
- The output impedance is about 0.02 ohm at the 5V end and 0.1 ohm at the 15V end of the range.
- Visiting several hi-fi shops, most units, including the 8 ohm types have a sensitivity of between 87db and 96b/mW.
- In order to set this for optimum sensitivity, a one ohm resistor should be connected across the probes and the control is adjusted until the l.e.d. just becomes illuminated.
- Ohm's Law comes to the rescue and we obtain a value of 0.4V/186A or 2.15k.
- Going back to headphones, to provide 10mW of pure class-A into a pair of 32 ohm "phones requires a voltage swing of 560mV r.m.s. and a current consumption of 25mA.
- A decade ago most stereo headphones were 8 ohm units, now most quality units employ Mylar film diaphragms and are usually rated 32 ohm impedance.
- First, as h/ez has the dimensions of the ohm, the unit of resistance, we can use a MOSFET as a resistance standard.
- Mr Roberts quotes typical values of capacitor and primary coil resistance of and 0.7 ohm respectively.
- Note also that an 8 ohm loudspeaker is needed.
- The current flowing in R6 can thus be determined from Ohm's Law.
- The low ohm, high wattage resistors used are wirewound types and should be available generally.
- The circuit shown in Fig. 2 (based on a comparator) will, however, detect changes in resistance of less than 0.1 ohm.
