ஒரு ஸ்பீக்கரில்.88 db.90 db. Sincuvity குறிப்பிட்டிருக்கும். சில ஸ்பீக்கரில் இது இருக்காது இல்லாத ஸ்பீக்கரில் எவ்வாறு எந்த வழிமுறை வைத்து கண்டுபிடிப்பது இதைப் பற்றி ஒரு வீடியோ போடவும்
No one has ever given this kind of explanation. I don't know how to thank you. How can I say Thanks to you? Very useful information, This will be clear if we can by do practical experience it.
Normally we test speaker coil using multimeter on ohms range.. For instance if it's reading is 4ohms we call it is 49h se ms impedance instead of 4ohms resistance...why we call it impedance instead of resistance sir...?
Ohmic resistance is the resistive force given to the flow of current through a wire. Longer the lengh more will be the resistance. But, when the current flows through a coil (inductor) or Transformer it sustains not only the ohmic resistance. It sustains also inductance, and inherent capacitance in between the turns of wire. So it is called in another term "Impedance", but measured in Ohms. Though Ohms is common measure for both ohmic resistance and impedance of coils, transformers, speakers etc. both are different.
