Hey friends!!
-----------------------------------------------------
Here is your answer↓
-----------------------------------------------------
=> It is given that:-
→ Voltage= 250 V.
→ Current = 0.4 A.
=> Power = V•I.
= 250 × 0.4
= 100 Joule.
=> Resistance= V/ I.
= 250/0.4
= 625 Ω.
☺☺☺ hope it is helpful for you ✌✌✌.

Given:v=250,I=0.4A
So, resistance=
R=V/I=250/0.4=625 ohm
So, resistance=
R=V/I=250/0.4=625 ohm
