1. If the external resistance of the ideal current source increases gradually, its terminal voltage () A. Gradually increase B. gradually decrease C. D. constant Better explain why
A.
Analysis: the concept of ideal current source is that no matter how the external circuit is, the output current of the power supply is constant, so when the resistance of the external circuit gradually increases, in order to keep the output current constant, the terminal voltage must be gradually increased
Does the voltage controlled current source have resistance in ideal state?
Do not say anything, as long as the component has resistance. The premise is the ideal state!
There is resistance and the impedance is very high
Current source outflow current how much, then the circuit current is how much. Has nothing to do with the voltage. The premise is the constant current source
Given the current of current source, the current of this line is constant, which has nothing to do with your load resistance
The internal resistance of the current source is larger than that of the load, and the fluctuation of the load impedance will not change the current. In the current source circuit, the series resistance is meaningless, because it will not change the load current or the load voltage
Why can a resistor connected in parallel with an ideal voltage source be regarded as open and a resistor connected in series with an ideal current source be regarded as short circuit?
Can the ideal voltage source be paralleled with the ideal current source!
Disconnection and series connection both refer to the resistance as a voltage and current source. The internal resistance is very large and the circuit current is very small. It seems that the disconnection resistance is very small and the circuit current is close to the current source. It seems that the ideal voltage and current source both refer to the internal resistance. The former is very large and the latter is very small
