These human capacities, in turn, directed technical decisions concerning voltage and current--whether, for example, one used three or eighteen milliamperes
for hair removal.
The generator, set at 45 kilovolts and 40 milliamperes
(mA), generated X-rays from a copper-target X-ray tube.
As Figure 7 shows, the current-mirror topology for biasing GaAs HBT power amplifiers requires tens of milliamperes
(mA) of control current and has a 6 mA/100 mV control sensitivity and +1000 ppm/[degrees]C temperature dependency.
The small contact area of the jack pads on the hard, high-resistivity limestone surface reduced the current flow to levels as low as 23 milliamperes
at 950 vac.
This includes inductance ranging from 0.10 to 47 microhenries, current ratings from 575 to 3,100 milliamperes
, and saturation current up to 4,500 milliamps.
All images were exposed using the Sirona DS intraoral X-ray unit (Sirona Dental Systems, Bensheim, Germany) operating at 7 milliamperes
(mAp) and 60 kilovolts (kVp) (constant potential).
Other features include operation on an active current of 30 milliamperes
and a standby current of just 200 microamperes and an ability to use a multi-chip package to add a flash memory device to the UtRAM.
Linear outputs of four to 20 milliamperes
and zero to 10 volts DC are provided for connection to displays, PLC's and SCADA systems.
20 is related to the radiant intensity of the beam per milliamperes
of beam current.
Beam currents, which control the available dose rate, vary with machine type and range from microamperes to several milliamperes
The stimulating current of most CES devices in the US has traditionally been limited to 1.5 milliamperes
A practical case design supports its rugged, compact, and accurate constitution, making it an ideal solution for measuring and stimulating millivolts, volts, milliamperes
, ohms, thermocouples and resistance thermometers.
