357129 Assertion :
Though the same current flows through the lines wires and the filament of the bulb but heat produced in the filament is much higher than that in line wires.
Reason :
The filament of bulbs is made of a material of high resistance and high melting point.

357130 Six similar bulbs are connected as shown in the figure with a \(DC\) source of emf \(E\) and zero internal resistance. The ratio of power consumption by the bulbs when (i) all are glowing and (ii) in the situation when two from section \(A\) and one from section \(B\) are glowing, will be :

357131 Drift speed of electrons, when 1.5 \(A\) of current flows in a copper wire of cross section \(5\,m{m^2},\) is \(v\). If the electron density in copper is \(9 \times {10^{28}}/{m^3}\) the value of \(v\) in \(mm/s\) is close to (Take charge of electron to be \( = 1.6 \times {10^{ - 19}}C\))

357132 Assertion :
If 10 bulbs are connected in series and one bulb fused then the remaining 9 bulbs will not work.
Reason :
Bulb of higher wattage will give less bright light.
