Question 9.5: Additional Answer Options

2021 - November - Paper 1 - Question 9

Or

Option 2

P_{\text{ave }}=V_{\text{rms }}I_{ms}

=(70,71)(2,83)

=200,11\mathrm{~W}

Or

Option 3

P_{\text{ave/gem }}=I_{ms/wgk}^2R

=(2,83)^2(25)

=200,22\mathrm{~W}

Or

Option 4

I_{\mathrm{rms}/wgk}=\frac{I_{\max/maks}}{\sqrt2}

2,83=\frac{I_{\max}}{\sqrt2}

\mathrm{I}_{\max/\text{ maks }}=4\mathrm{~A}

\mathrm{P}_{\mathrm{ave}/\mathrm{gem}}=\frac{\mathrm{V}_{\text{max }/\mathrm{maks}}\mathrm{I}_{\text{max/maks }}}{2}

=\frac{(100)(4)}{2}

=200\mathrm{~W}
