Ein Widerstand (\SI{56}{\ohm}) aus Gold wird \SI{50}{\celsius} erhitzt. Wie viel ändert sich sein Widerstand?

Solution

\newqty{R}{56}{\ohm} \newqty{Dt}{50}{\celsius} \newqty[per-mode=reciprocal]{a}{4.0e-3}{\per\kelvin} \solqty{DR}{R_0 \cdot \alpha \cdot \Delta\theta}{\Rn*\an*\Dtn}{\ohm} \al{ \Delta R &= \DRf \\ &= \R \cdot \a \cdot \Dt \\ &= \DRTT }
