Homework Statement
A heater rated at 2000 W operating at 250 V is used on a supply of 230 V. If the resistance of the heater is independent of temperature, calculate the power absorbed by the heater.
Homework Equations
[tex]P=\frac{V^2}{R}[/tex]
The Attempt at a Solution
resistance of heater :
[tex]R=\frac{V^2}{P}=31.25~ \Omega[/tex]
The power absorbed :
[tex]P'=\frac{230^2}{31.25}=1692.8 ~W[/tex]
Do I get it right?
Thanks
