Two similar capacitors are first connected in parallel and then in series what is the ratio in the two cases?
Two similar (non-polarized) capacitors connected in parallel will have double the capacitance of one, while two similar capacitors connected in series will have half the capacitance of one, so the ratio is four.
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 do you make a non-polarized electrolytic capacitor?
Take two electrolytic capacitors of the same voltage and capacity, connect the positive leads together and connect the negative leads to the circuit. Just keep in mind that this will reduce the cap. value by half (2, 1000uF caps = 500uF) Also the voltage of the circuit should not exceed the voltage of one of the caps.
What capacitors are polarity sensitive?
While most electrolytic capacitors are the ones that have a polarity noted as minus "-" and "+" as opposed to ceramic or film capacitors, it's important to note that even electrolytic capacitors could also be labelled as "np" for non-polarized or "bp" bi-polarized, which means the same thing, that there is no plus or minus and the current can flow in both directions. Today a good quality electrolytic, most of the time, will be another color to depict this such as green for example, whereas in older circuits they could sometimes look identical but just be missing the little "-" indicator. So, you need to pay attention to this little detail on older boards when replacing a capacitor.
Do electrolytic capacitors generally have polarity?
Yes. Electrolytic capacitors are polarized. Capacitors with positive and negative poles generally have positive and negative marks. Generally, for capacitors with pins, the long end of the pin is the positive electrode. For cylindrical electrolytic capacitors, there will be a vertical line printed on the negative side of the capacitor. SMD capacitors generally have no positive and negative poles. --- We're JYH HSU(JEC) Electronics Ltd (or Dongguan Zhixu Electronic Co., Ltd.), an electronic components manufacturer.

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.
What is a non polarized capacitator?
bipolar capacitors
What is the difference between normal and bipolar electrolytic capacitors?
The difference is that bipolar capacitors are two polarized electrolytes coupled head to toe.Normal capacitors are film based and show better electrical properties.
What is an unpolarized capacitor?
A capacitor that does not have a designated + and - side. Electrolytic capacitors are usually polarized. Ceramic capacitors are not.
Are tantalum capacitors polarized?
Yes, tantalum capacitors are polarized capacitors.This means that when connecting them in a circuit, you must connect the anode to the higher positive voltage than the cathode.
Two similar capacitors are first connected in parallel and then in series what is the ratio in the two cases?
Two similar (non-polarized) capacitors connected in parallel will have double the capacitance of one, while two similar capacitors connected in series will have half the capacitance of one, so the ratio is four.
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.
What type of capacitor is normally polarized?
There are many different cpacitor technologies, or 'types'. To name a few, there are Electrolytic, Ceramic, Polypropylene Film, and Metalled Paper capacitors. The only type of capacitor commonly polarized are Electrolytic Capacitors. This means DC supply only. Dealing with AC? I'd recommend ceramic.

In the input and output side,the positive side opposes the Vcc supply (dc).
Why using electrolytic capacutor for dc voltage?
Electrolytic caps are polarized and come in larger voltage rating and larger cap size than other types of capacitors.
What are the Darwbacks of non-polar capacitor over polar capacitor?
A: Polarized capacitors can be smaller in size as compared to a non polarized in the same capacity
What is the symbol of non-polar capacitors?
Two straight parallel lines. One straight, and one curved is often used to denote a polarized capacitor.
