A) 220 V
B) 225 V
C) 240 V
D) 260 V
Correct Answer: B
Solution :
The resultant of potential differnece \[V=E-IR\] or \[E=V+IR\] or \[E=V+I\times \frac{P}{{{I}^{2}}}\] or \[E=V+I\times \frac{P}{{{I}^{2}}}\] \[E=220+4\times \frac{20}{{{(4)}^{2}}}\] \[=225\,V\]You need to login to perform this action.
