flame current measurement
... This principle can be used for flame sensing, by making the two electrodes unequal. If one electrode is at least 4 times larger than the other, the current in both halves of the sine will not be equal. This is caused by the difference in mobility due to size and weigth of the positive and negative p ...

Current source
A current source is an electronic circuit that delivers or absorbs an electric current which is independent of the voltage across it.A current source is the dual of a voltage source. The term constant-current 'sink' is sometimes used for sources fed from a negative voltage supply. Figure 1 shows the schematic symbol for an ideal current source, driving a resistor load. There are two types - an independent current source (or sink) delivers a constant current. A dependent current source delivers a current which is proportional to some other voltage or current in the circuit.
