... A graphite lead from a pencil can be used as well. ATTENTION – graphite behaves as a semiconductor – its resistivity decreases with growing temperature. So the lead initially seems not to conduct but as it gets heated, its resistivity decreases and it begins to glow. If the lead does not glow but on ...

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.
