Q. Consider a circuit comprising only resistors with constant resistance and ideal independent DC voltage sources. If all the resistances are scaled down by a factor 10, and all source voltages are scaled up by a factor 10, the power dissipated in the circuit scales up by a factor of

Sol:

Let the equivalent circuit is:

Resistance is scaled down by a factor 10 and source voltage is scaled up by a factor 10.

Hence, power dissipated in the circuit scales up by a factor of 1000.
