Transistors $ \text{Q1 and Q2} $:
- $ \text{B} $ (Base) - For both transistors, $Q1:B$ is connected to $R5:P2$ and $Q2:B$ is not directly specified in the nets. Since the base of a transistor is a control pin, it's usually not left floating to ensure that the transistor remains off when not explicitly driven. However, your project shows $Q1:B$ connected, so we assume a typo or omission for $Q2:B$. Using a pull-up or pull-down resistor depends on the desired default state of the transistor.
- $ \text{E} $ (Emitter) - Both emitters are connected; $Q1:E$ is part of a net connecting it to $R1:P1$, and $Q2:E$ connects to $R4:P1$.
- $ \text{C} $ (Collector) - For $Q1:C$, there is no mention of a connection, which might be intentional based on your circuit design. The collector's connection often depends on the load it drives; it could be connected to a supply voltage through a load. $Q2:C$ connects to $R3:P2$.
-
Resistors have all been accounted for in your nets, indicating where each pin of resistors $R1$, $R2$, $R3$, $R4$, and $R5$ connects, with none mentioned as unconnected.
Recommendations-
For Transistor $Q2:B$: If it is indeed unconnected, a pull-down resistor is commonly used for NPN transistors to ensure it remains off when not driven. The assumption is $Q2$ is an NPN transistor because you haven't specified otherwise. The value of this resistor can typically range from $10k\Omega$ to $100k\Omega$, ensuring minimal current draw while providing enough of a signal to keep the transistor turned off.
-
For Transistor $Q1:C$: If its connection isn't mentioned because it's indeed unconnected, you need to analyze the intended function. For output or switch transistors, the collector is usually connected to a load. If it's intentionally left open for part of a design phase, no pull-up or pull-down resistor is necessary here.
