#### Lösungsweg
|
||||
<left>
|
||||
* gegeben: $R = 150Ω$
|
||||
* gegeben: $R_S = 4\cdot 150Ω = 600Ω$
|
||||
* gegeben: $R = \qty{150}{\ohm}$
|
||||
* gegeben: $R_S = 4\cdot \qty{150}{\ohm} = \qty{600}{\ohm}$
|
||||
</left>
|
||||
<right>
|
||||
* gegeben: $R_{ges} = 50Ω$
|
||||
* gegeben: $P_R = 1W$
|
||||
* gegeben: $R_{ges} = \qty{50}{\ohm}$
|
||||
* gegeben: $P_R = \qty{1}{\watt}$
|
||||
* gesucht: $n$ Widerstände, $P$
|

Reihen mit je 4 Widerständen:
|
||||
$\frac{1}{R_{ges}} = n_S \cdot \frac{1}{R_S} \Rightarrow n_S = \frac{R_S}{R_{ges}} = \frac{600Ω}{50Ω} = 12$
|
||||
$\frac{1}{R_{ges}} = n_S \cdot \frac{1}{R_S} \Rightarrow n_S = \frac{R_S}{R_{ges}} = \frac{\qty{600}{\ohm}}{\qty{50}{\ohm}} = 12$
|
||||
$n = 4 \cdot n_S = 4 \cdot 12 = 48$
|
||||
</fragment>
|
||||
<fragment>
|
||||
$P = n \cdot P_R = 48 \cdot 1W = 48W$
|
||||
$P = n \cdot P_R = 48 \cdot \qty{1}{\watt} = \qty{48}{\watt}$
