Hanyar Lissafin Juriya
Lissafin jimlar juriya a cikin da'irar jeri ya ƙunshi amfani da dokar Ohm da dokokin Kirchhoff. Ga misalan lissafin juriya a cikin da'irori jeri da layi ɗaya:
Misali na 1: Da'irar Jeri
A ce muna da juriya guda uku a jere tare da juriya \( R_1 = 10 \Omega \), \( R_2 = 20 \Omega \), da \( R_3 = 30 \Omega \). Jimillar juriya ita ce:
\[ R_{\text{jimlar}} = R_1 + R_2 + R_3 \]
\[ R_{\text{total}} = 10 \Omega + 20 \Omega + 30 \Omega \]
\[ R_{\text{total}} = 60 \Omega \]
Misali na 2: Layi Mai Layi
A ce muna da juriya guda uku a layi daya da juriya \( R_1 = 10 \Omega \), \( R_2 = 20 \Omega \), da \( R_3 = 30 \Omega \). Jimillar juriya ita ce:
\[ \frac{1}{R_{\text{total}}} = \frac{1}{R_1} + \frac{1}{R_2} + \frac{1}{R_3} \]
\[ \frac{1}{R_{\text{total}}} = \frac{1}{10 \Omega} + \frac{1}{20 \Omega} + \frac{1}{30 \Omega} \]
\[ \frac{1}{R_{\text{total}}} = 0.1 + 0.05 + 0.0333 \]
\[ \frac{1}{R_{\text{total}}} = 0.1833 \]
\[ R_{\text{total}} = \frac{1}{0.1833} \]
\[ R_{\text{total}} \approx 5.46 \Omega \]
