... Plotting the behavior as a function of frequency (see Figure 3), you will find that the amplitude of VC (t) vanishes, while the amplitude of VR (t) goes to Vs , while the phase difference between the applied voltage and resulting current also vanishes. You can prove this by taking the limits of the ...

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.
