current source vs voltage source-Difference between current source and voltage source
This page on current source vs voltage source describes basic difference between current source vs voltage source.
Figure-1 depicts ideal current source and practical current source.
Ideal Current Source:
Current always remains constant for any value of voltage across it.
Ideal Current Source: It has large value of internal resistance. Current varies with respect to the voltage across the element.
Figure-2 depicts ideal voltage source and practical voltage source.
Ideal Voltage Source: Voltage always remains constant for any value of current passing through it.
Practical Voltage Source: It has small internal resistance. Voltage across the element varies with respect to the current.
