A few days later, he got the idea of using a direct resistance instead of a constant current source, and found that it worked.

In this connection, when the supply voltage varies, the voltage drops across the collector resistors change slightly ( in the case of emitter constant current source, they do not change at all ).
13.
In many cases the internal heat source may be modelled with a constant current source, rather than a voltage, giving a better analogy of power loss as heat, rather than assuming a simple constant temperature.
14.
From those who opt to restrict their use as active devices to those who opt to include them in the audio circuit, accepting the use of semiconductor gain devices in the power supply or as constant current sources.
15.
Else, if You are using the LED as light for IR camera, You need either synconize the pulse to the captured picture or use a linear constant current source what might be fed from a buffered stepdown converter.
16.
Power supply is reconfigured into a constant current source, usually with a massive, high-inductance anode choke ( gapped inductor ), so there is little, if any, gain in cost and weight of magnetic components.
17.
Some battery types have high tolerance for overcharging ( ie, continued charging after the battery has been fully charged ) and can be recharged by connection to a constant voltage source or a constant current source, depending on battery type.
18.
When the supply of ions does not meet the demand created by the potential the resistance increases, the effect being that of a constant current source or sink, and the cell is then said to be polarized at that electrode.
19.
The output is taken from the cathode of the top ( not directly driven ) device, which acts part way between a constant current source and a cathode follower but receiving some drive from the plate ( anode ) circuit of the bottom device.
20.
The bombarding current is provided by a large transformer with an open-circuit voltage of roughly 15, 000VAC to 23, 000VAC . The bombarding transformer acts as an adjustable constant current source, and the actual voltage during operation depends on the length and pressure of the tube.
