Power = Voltage × Current
P = V x I
Where , I = 0.25amp = 25 / 100 amp = 1/4 amp and V = 244V
P = 244 x 1 / 4 = 61 watt
So, Power rating of lamp = 61 w.
P = V x I
Where , I = 0.25amp = 25 / 100 amp = 1/4 amp and V = 244V
P = 244 x 1 / 4 = 61 watt
So, Power rating of lamp = 61 w.

P=v^2/R
V=IR
R=V/I
=61ohm
Now, P=244×244/61
=976watt
V=IR
R=V/I
=61ohm
Now, P=244×244/61
=976watt
