A) 8000Wh
B) 2000Wh
C) 1000Wh
D) 500Wh
Correct Answer: C
Solution :
Here: Resistance\[R=80\,\Omega \]. Voltage\[V=200\]volt Time \[t=2\text{ }hr\] The relation for power is given by \[D=P=\frac{{{V}^{2}}}{R}=\frac{{{(200)}^{2}}}{80}\] =500 watt Hence, the energy spent is = power\[\times \]time \[=500\times 2\] \[=1000\text{ }Wh\]You need to login to perform this action.
