【单选题】A basic characteristic for an ideal independent voltage source is:
A.
the voltage across it has no relationship with the current flowing through it, the current can be any value and is decided by the source and the external circuit.
B.
the voltage across it has relationship with the current flowing through it, the current can ‘t be any value and is decided by the voltage source.
C.
the voltage across it has no relationship with the current flowing through it, the current can be any value and flows out from the positive terminal of the voltage source.
D.
the voltage across it has relationship with the current flowing through it, the current can be any value and may flow out of any terminal of the voltage source.
【判断题】An ideal voltage source is a circuit element that maintains a prescribed voltage across its terminals regardless of the current flowing in those terminals.
