... Resistance is the property of a material which restricts the flow of electricity. Energy is converted into other forms (e.g. light, heat), as the voltage across the component drives the current through it. The unit of resistance is the Ohm (Ω). What causes resistance?

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.
