A) 8000Wt
B) 2000Wt
C) 1000Wt
D) 800Wt
Correct Answer: C
Solution :
Here: Resistance\[R=80\text{ }\Omega \] Voltage \[V=200V\] Time \[t=2\,hr\] The relation of power is given by as \[P=\frac{{{V}^{2}}}{R}=\frac{{{(200)}^{2}}}{80}\] \[=500\text{ }W\] Hence, energy spent is given by = power\[\times \] time\[=500\times 2=1000\text{ }Wh\]You need to login to perform this action.
