Whakaoti i te 1/R_{1}-1/R_{2}

$$\frac { 1 } { R _ { 1 } } - \frac { 1 } { R _ { 2 } }$$

Aromātai

$$\frac{R_{2}-R_{1}}{R_{1}R_{2}}$$

Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Ko te taurea pātahi iti rawa o R_{1} me R_{2} ko R_{1}R_{2}. Whakareatia \frac{1}{R_{1}} ki te \frac{R_{2}}{R_{2}}. Whakareatia \frac{1}{R_{2}} ki te \frac{R_{1}}{R_{1}}.

$$\frac{R_{2}}{R_{1}R_{2}}-\frac{R_{1}}{R_{1}R_{2}}$$

Tā te mea he rite te tauraro o \frac{R_{2}}{R_{1}R_{2}} me \frac{R_{1}}{R_{1}R_{2}}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{R_{2}-R_{1}}{R_{1}R_{2}}$$

Tauwehe

$$\frac{-\frac{R_{1}}{R_{2}}+1}{R_{1}}$$
