Why the two capacitors must have their positive terminal toward the transistor in the amplified circuit?

they don't; it's just a convention
capacitors include polarized and non-polarized
with non-polarized one, no one will know if you soldered it in backward; it's exactly the same
polarized ones can be damaged by a backward voltage (but simply lining up plus/plus and minus/minus is not any guarantee)
The positive side of electrolytic capacitors blocks the dc current entering.
In the input and output side,the positive side opposes the Vcc supply (dc).

How we can identify emmiter in transistor?
The method of identification differs in different type of capacitors. In cylindrical type, the emitter is the terminal nearest to i small notch present. In flat type, its printed on the transistor itself.
What is the difference between upstream and downstream in electrical network?
Generally upstream is closer to the positive (+) voltage source. In the case of an NPN transistor upstream of the transistor is the part of the circuit from (+) to the NPN collector pin. Downstream of the transistor is from the NPN emitter pin to the ground / sink / negative (-) terminal.
How do you tell what end is positive on capacitor?
there are a number of different types of capacitors, each with its own identification. on common electrolytic capacitors the negative terminal is shorter and the side with the negative terminal is marked with a white line. note that ceremic capacitors are bipolar. ie. it doesnt matter which way they are connected. thse are shpaed like a bean and are commonly brown or green. if in doubt look up the data sheet for the component. just type in the identification on the capacitor into a search engine.
Why UJT is called as transistor?
Even though it has only two types of charge carriers we will not call it as a diode but a transistor since it is a three terminal device.
What is the positive terminal of a diode known as?
It is called the positive + terminal or post, just like you list. Electrons flow for the negative - to the + terminal contrary to popular belief.Another AnswerAs electrons flow through the external circuit from anode (negative terminal) to the cathode (positive terminal) , then the answer is 'cathode'.
Why is it important that the two capacitors must have there positive terminal toward the transistor?
Capacitors if polarized care less about a transistor or other devices all they care that the proper polarities are applied.
Why is it important that the two capacitors must have their positive terminal toward the transistor?
A: It is not important what is important it that the capacitor has the correct polarity across its terminals otherwise it will not function correctly

Do capacitors have positive and negative?
Some capacitors have terminals as they are polarized but some have not as they are not polarized. you can easily identify a polarized capacitor as it has + or - terminal indication marked.
Why is the polarity of capacitors in RC coupled amplifiers such that the negative terminal receives the input signal?
The input signal is assumed to have zero DC bias. Input stages will typically have a positive bias on the base or grid, respectively, of the first stage transistor or tube. So, the input terminal is more negative. ANSWER: The polarity of the capacitor is determined by the bias polarity as used. If the bias is negative then the capacitor negative terminal must be connected to it.
What is the difference between upstream and downstream in electrical network?

What does a transistor look like?
Transistor is a three terminal device. Its shape may differ with applications.
How do you reset the service engine light on your 1992 wrangler?
Disconnect the POSITIVE battery cable and touch it to the negative terminal OR disconnect the POSITIVE battery cable for about 30 minutes (either way drains the capacitors in the electrical system)
What is positive about batteries?
One terminal is positive and the other terminal is negative. The positive terminal is slightly larger.
Which terminal of a bipolar transistor has the current direction arrow?
The emitter

What is the difference between a positive terminal and negative terminal of a battery?
The positive + terminal is slightly larger.
