5. Radha had been using an inexpensive filament-based light bulb which gives off yellow/orange light to lit her room. Now, as she has started earning, she wants to bring home a tubular lamp which involves a two-step process of generation of light and gives off white light after blinking for a few seconds. Identify the lightinper her requirement.

A 60 w bulb has a filament temperature of 2000 K. what will be the wattage of another bulbs of same filament area and material at a temperature of 400

Correct Answer - D `(P_(2))/(P_(1))=(T_(2)^(4))/(T_(1)^(4))=((4000)/(2000))^(4)=16` `P_(2)=16xxP_(1)=16xx60=960w` `P=sigma A rhoT^(4)`

A current `I=3 sin omega t` ampere flows through a bulb. The P.D. across the bulb is given by `V=4 cos omega t` volt. The power dissipated in the bulb

Correct Answer - C `V = 4 cos (omega t) = 4 sin (omega t +(pi)/2)` Phase diff. between V and I is `(pi)/2` `:.` Power factor = `cos(pi)/2 = 0`.

A filament bulb `(500 W, 100 V)` is to be used in a `230 V` main supply. When a resistance `R` is connected in series, it works perfectly and the bulb

Correct Answer - C If a rated voltage and power are given, then `P_("rated") = (V_("rated")^(2))/R` `therefore` Current in the bulb, `I=P/V` `[therefore`P=VI] `I= 500/100= 5A` `therefore` Resistance of bulb, `R_(b)...
