A) 625 \[\Omega \]
B) 0.25 \[\Omega \]
C) 6.25 \[\Omega \]
D) 62.5 \[\Omega \]
Correct Answer: D
Solution :
From \[P=\frac{{{V}^{2}}}{R}\] or \[R=\frac{{{V}^{2}}}{P}\] ...(1) Here, \[V=250volt,\text{ }P=1kW=1000\text{ }watt\]. From equation (1), \[R=\frac{250\times 250}{1000}=62.5\Omega \]You need to login to perform this action.
