Connecting transistor to battery terminal

Hi all,

At first, when connecting a capacitor and resistor, any ends can be used because I thought the two components are not polarised. Am I correct in saying this?

But also, I'm worried that with my transistor being polarised, I'll need to proceed with more caution.
 
Hello,

You are not completely correct about the capacitor.
Electrolitic and tantalium capacitors do have a polarity.
When mounted in reverse, they can blow up.
As for transistors, it depends on wich you are using.
In NPN transistors, the collector should have a higher potential as the emittor.
In PNP transistors, the collector should have a lower potential as the emittor.
Have a look at chapter 3 of the following book:
