I am reading The Art Of Electronics, and I realize this is more of an encyclopedia rather than a textbook. I have referenced other sources as this has mainly served as a compass for me to learn about each subject area. My question is fairly simple and straightforward. I'm using multisim to replicate a circuit that was provided in the book. The author used a simple transistor switch to light an LED, to explain the function of a BJT. When I went to simulate the circuit, the LED lights up, even though it should not, at least until the SPST is closed. What is causing the transistor to act like a short? As far as I understand it, the collector is an open circuit, until the point in which the VB ≈ VE + VBE, at which point the collector would be saturated.
