Seriekoppling/Parallellkoppling - resistorer

$$R_{\text{ total}} = R_1 + R_2 + ... R_n$$

• $R_{\text{ total}}$ = Total resistansen
• $R_i$ = Del resistans i

$$\frac{1}{R_{\text{ total}}} = \frac{1}{R_1} + \frac{1}{R_2} + ... + \frac{1}{R_n}$$

• $R_{\text{ total}}$ = Total resistans
• $R_i$ = Del resistans i
