Introduce voltage noise to a current source



This is in Multisim Live. I've been trying to simulated adding voltage noise to a current source's output. I thought it would be possible to add a voltage source in series to simulate a constant frequency noise as shown in the circuit above, but this has no affect at all. No matter what magnitude or frequency I set the voltage source to, it has no effect on the output. I have searched but haven't found an answer as to why this doesn't work. Is there something I'm doing wrong?

Привет! Поскольку источник тока имеет бесконечное сопротивление(почти), нужно источнику шума задать сопоставимое сопротивление, чтобы на осциллографе и синус, и шум были видны...
