that power dissipated in the 2$\Omega$ resistor is maximum. Under
this condition:

• A. R $=$ 0
• B. R $=$ 8$\Omega$
• C. power dissipated in the 2 $\Omega$ resistor is 72 W.
• D. power dissipated in the 2 $\Omega$ resistor is 8 W.

Answer 1

Answer: (A), (C)

The correct options are
A R $=$ 0
C power dissipated in the 2 $\Omega$ resistor is 72 W.
