Solved Questions on Current Electricity in Bengli (চলত্বড়িৎ )

-

 

এই পোস্ট টিতে আমরা চলত্বড়িৎ সমন্ধে কিছু প্রশ্নের উত্তর খুঁজবো৷

প্রশ্ন:  একটিপরিবাহীর মধ্য দিয়ে (1/2)মিনিট ধরে 90 কুলম্ব আধান প্রবহিত হলে পরিবাহীর প্রবাহমাত্রা নির্ণয় করো৷

উত্তর:

আমরা জানি, 

 

 

আধান = 90 কুলম্ব

সময় = (1/2) মিনিট = (60/2) সেকেন্ড =30 সেকেন্ড

প্রবাহমাত্রা = (90/30) অ্যাম্পিয়ার= 3 অ্যাম্পিয়ার


প্রশ্ন: একটি পরিকাহীর প্রস্তচ্ছেদ 0.2 সেমি2 এবং অন্য একটি পরিবাহীর প্রস্তচ্ছেদ 0.4 সেমি2 ৷ পরিবাহী দুর্টির মধ্য দিয়ে 1 ঘণ্টা ধরে 3600 কুলম্ব আধান প্রবাহিত হলে কোন্ পরিবাহীর প্রবাহমাত্রা বেশি হবে ৷

 উত্তর:

প্রবাহমাত্রা বলেতে বোঝায় একটি পরিবাহীর প্রস্তচ্ছেদের মধ্য  দিয়ে  যত পরিমান আধান একক সময়ে প্রবা্হিত হয় ৷

 

এখনে, প্রত্যেকটি পরিবাহীর মধ্য দিয়ে 1 ঘণ্টায় 3600 কুলম্ব আধান প্রবাহিত হয় ৷ 

সেই কারনে,  দুটি পরিবাহীর প্রবাহমাত্রা সমান ৷

FUNCTION OF BASS, TREBLE, VOLUME OPTION IN AN AMPLIFIER

-
Image
Bass and Treble options are used to regulate the sound on the basis of frequency.  Generally a audio amplifier has 3 main controlling options. (i) Volume or Master  (ii) Bass (iii) Treble Volume : When we increase Volume the loudness of the audio is increased. In frequency level, the amplitude of all the frequencies are increased.  Similarly, when we decrease Volume, the loudness is decreased i.e. amplitude of all the frequencies are decreased. Bass : When we increase Bass, the loudness of only lower frequencies are increased i.e. amplitude of the lower frequencies are increased. When we decrease Bass, the loudness of only lower frequencies are decreased i.e. amplitude of the lower frequencies are decreased. Treble : When we increase / decrease the Treble, the loudness of the sound of only higher frequencies are increased / decreased. Now the main questions is that what do lower and higher frequencies mean ? We know that human beings able to h...

Purity Test of Purified Water (For School & College level lab practical)

-
Purity Test of Purified Water Requirement : Test tube, test tube holder, test tube rack, labeling materials (pen, paper, scissors, gum).  Reagent : Litmus paper (red and blue), BaCl 2 , AgNO 3 , Ammonium Oxalate, NH 4 OH, Nessler's Reagent, Sodium Sulfide, Ingredients: Supplied purified water.  Procedure: Experiment 1: Some amount of purified water is taken in a test tube.  Observation : Clean, colorless, odorless. Inference : May be pure. Experiment 2: Litmus Test: Some amount of purified water is taken in a clean test tube. (a) A blue litmus paper is dipped into the solution. (b) A red litmus paper is dipped into the solution.  Observation : (a) The colour of blue litmus paper is not changed. (b) The colour of red litmus paper is not changed. Inference : (a) Absence of Acid. (b) Absence of alkali. Experiment 3: Some amount of purified water is taken in a test tube. Few ...

KNOW ABOUT BASIC ELECTRICAL AND ELECTRONIC DEVICES

-

Nowadays, we are familiar with the, electricity and various electrical instruments. There are many things  e.g light, fan, TV, refrigerator,switch,fuse etc. in our house. We use this instruments. But we frequently listen some terms and devices name viz. voltage, current, AC Current, DC Current, resistor, transformer, capacitor, LED, inductor etc . which we don't use these directly. But, amazing fact is that, the instruments which we daily use, are made of these(resistor, capacitor etc.).  Let's discuss these. Here, I don't discuss these so deeply. What is Voltage? and  What is Current? Voltage( Potential difference) represents the force. And Current represents the flow of electrons in the circuit. We (who are the basic users or novice) need not know much about this. It is a image of mobile charger.See what is written as input and output The unit of voltage is volt ( v ) and current is ampere ( A ). 1mA=(1/1000) A You obviously heard the term...
