Answer 1

Answer:

In the circuit shown in the figure, the resistance marked R can be varied by using a Rheostat. The power across the 5 Ω resistor will be maximum if the Rheostat has a resistance equal to  zero

Explanation:

Maximum power transfer theorem. Current through 5 Ω resistor is maximum if R = 0.

In this case, the power through 5 Ω resistor will be maximum.
