Chapter 6: Transistors and Gain
Bipolar transistors come in two basic types: npn and pnp. The current flow in a npn transistor shown schematically in the accompanying figure 6.2, below. Current (conventional, positive) goes in through the base terminal and out the emitter and the amplified current flows from the collector to …

physics.wm.eduto the operation of the power supply used to power breadboard circuits in the Physics 252 laboratory course. Thévenin's theorem states that any linear power supply can be represented as an ideal voltage source in series with a single resistor, regardless of the inner workings and engineering of the supply [1]. This powerful theorem allows circuit
Chapter 3: Capacitors, Inductors, and Complex Impedance
physics.wm.eduChapter 3: Capacitors, Inductors, and Complex Impedance - 21 - To study a constant supply voltage on an RC circuit, we set the left side of equation 3.12 equal to a constant voltage. Then we have a simple homogeneous differential equation with the simple solution for the current of a decaying exponential, I I e /(t RC) 0
