This is 100% correct answer.

60W Lamp is having more Resistance......
1500W Lamp is having Low Resistance......
B'coz 1500W lamp having low resistance mean, High Current
Flow through the Lamp(Tungsten Filament)....

if V=220Volts,


60w Lamp:
Power=VxI
I= Power/V
I= 60/220
I= 0.2727Amps

1500w Lamp:
Power=VxI
I= Power/V
I= 1500/220
I= 6.818Amps

So 1500w Lamp getting high Current

Now we find the Resistance of Each Lamp,

As Per Ohms Law, V = IR

60w Lamp
V = IR
R = V/I
R = 220/0.2727
R = 806.6667Ohms
Resistance of the 60w Lamp is 806.667Ohms

1500w Lamp
V = IR
R = V/I
R = 220/6.818
R = 32.2675Ohms
Resistance of the 1500w Lamp is 32.2675Ohms

Resistance of the 60w Lamp is 806.667Ohms
Resistance of the 1500w Lamp is 32.2675Ohms

Therefore 60w Lamp Get More Resistance than 1500w Lamp
