ব্যাখ্যা: ব্যাখ্যা: In parallel connection, the voltage across the element is constant. Therefore, the voltage across heater remains same.

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

ব্যাখ্যা: 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.

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