ব্যাখ্যা: Kirchhoff's Current Law (KCL) is Kirchhoff's first law deals with the conservation of charge entering and leaving a junciton

ব্যাখ্যাঃ if two equal resistance connected in series across a certain supply are now connected in parallel across the same supply, the power produced will be four times that of series connection.

ইলেকট্রিক ডিহিউমিডিফায়ারের কাজ হলো বাতাসের জলীয়কণা শোষণ করে এবং আর্দ্রতাকে কমিয়ে ঘর, আসবাবপত্র ও যন্ত্রপাতিকে রক্ষা করা।

ব্যাখ্যাঃ When you give 5Hz supply, frequency is too low. Normally when 50 Hz (50 times a second AC is given, it will get max volts twice in each cycle, that is it gets varing voltage from 0 to 220'a hundred times a second, in negative and positive cycles), the white hot blulb filament has no time to cool. Hence it appears to us as glowing continuously. But when you drastically reduce to 5 Hz it has times to cool off and again get white when hot. You will observe the blub will flash at rate of 10 times per seconde

ব্যাখ্যা: Powers are additive in both series and Parrallel. Currents are additive in parallel circuits whereas voltages are additive in series circuit.
