183- In the circuit below, when the sliding rheostat moves from point A to point B, how do the power consumed by resistance $R_1$ and the output power of the generator change, respectively? [Figure: Circuit with sliding rheostat between points A and B, resistance $R_1$ in parallel, and a battery with internal resistance $r = 2\,\Omega$ and EMF $\varepsilon$, with $R_2 = 6\,\Omega$]
