A) 1100 W
B) 550W
C) 2200 W
D) (2200/3) W
Correct Answer: B
Solution :
(b) 550 W Here, \[V=220\,V\] Resistance, \[R=22\,\Omega \] Impedance, \[Z=44\,\Omega \] Current in circuit, \[l=\frac{V}{Z}=\frac{220\,V}{44\,\Omega }=5\,A\] Power dissipated in the circuit, \[P={{l}^{2}}R={{(5)}^{2}}\times 22=550\,W\]You need to login to perform this action.
