Question

What is the total power delivered to the circuit shown in figure ?

• A. 220 W
• B. 200 W
• C. 228 W
• D. 240 W

Answer 1

Answer: (C)

228 W

As $V_{AB}=V_{CD}$

$\therefore$ $(I-4)4=\left(4\right)2$ $⟹I=6$ A

$\therefore$ Total power delivered $P=I^{2}5+(I-4{)}^{2}4+4^{2}2$

$\therefore$ $P=6^2\left(5\right)+2^2\left(4\right)+4^2\left(2\right)=228$ W
