Let R_(1) be the resistance of 100W, 250V lamp and R_(2) be that of 200W, 250V lamp connected in series across a 500V line. Which of the following is correct?

In the figure shown B_(1),B_(2)" and "B_(3) are three bulbs rated as (200V, 50 W), (200V, 100W) and (200V, 25W) respectively. Find the current through each bulb and which bulb will give more light ?

Out of the four bulbs of marking (i) 100V,40W (ii) 200V,40W (iii) 100V,60W (iv) 200V,60W ,which bulb has highest resistance

Two bulbs of (40W 200V) and (100W 200V). Then correct relation for their resistances:

Two bulbs of (40W 200V) and (100W 200V). Then correct relation for their resistances:

Bulb B_1(100W - 250V) and bulb B_2(100W - 200V) are connected across 250V. What is potential drop across B_2 ?

Bulb B_1(100W - 250W) and bulb B_2(100W - 200V) are connected across 250V. What is potential drop across B_2 ?

Two incandescent lamps (25 W , 120 V ) and (100W , 120 V ) are connnected in series across a 240 V supply . Assuming that the resistances of the lamps do not vary with current ,find the power dissipated in each lamp after the connection .
