Answer:
400 Ohm.
Step-by-step explanation:
P = V ×V/R
1 = 200×200/R
1 = 400/R
R = 400 Ohm.

R is 40Ω
P = 1kw = 1000watt
v = 200v
P = VI
and I = V/R
Therefore,
P = V × V/R
= V²/R
1000 = 200×200/R
R = 40000/1000
= 40Ω
P = 1kw = 1000watt
v = 200v
P = VI
and I = V/R
Therefore,
P = V × V/R
= V²/R
1000 = 200×200/R
R = 40000/1000
= 40Ω
