Ideal constant current source
The DC Current Source block represents an ideal current source that is powerful enough to maintain specified current through it regardless of the voltage across the source.
You specify the output current by using the Constant current parameter, which can be positive or negative.
The positive direction of the current flow is indicated by the arrow.
Output current. You can specify positive or negative values.
The default value is
The block has two electrical conserving ports associated with its terminals.
