\(R_{tđ}=R_1+R_2=9+9=18\Omega\\ I=\dfrac{U}{R_{tđ}}=\dfrac{18}{18}=1A\)

b. K đóng

\(R_{tđ}=\dfrac{\left(R_1+R_2\right).R_3}{R_1+R_2+R_3}=\dfrac{\left(9+9\right)18}{9+9+18}=9\Omega\\ I=\dfrac{U}{R_{tđ}}=\dfrac{18}{9}=2A\)

\(P=\dfrac{x+2\sqrt{x}+x-2\sqrt{x}}{x-4}.\dfrac{x-4}{-2\sqrt{x}}=\dfrac{2x}{-2\sqrt{x}}=-\sqrt{x}\)

\(P=-\sqrt{x}=-\sqrt{4}=-2\left(đpcm\right)\)
