Isixhobo sokubala soRhwebo lwexabiso
Xa amathuba aphezulu kwisiphumo ngasinye, athathwe kubabhejisi abahlukeneyo, ebonisa ngaphantsi kwe-100% iyonke, izabelo zinokwahlulwa ukuze kufumaneke isivuno esifanayo nokuba kwenzeka ntoni. Amathuba angu-2.10 kunye no-2.05 kumacala omabini aqinisekisa u-3.73%.
Indlela esebenza ngayo
- Isixa = 1 / amathuba 1 + 1 / amathuba 2 (+ 1 / amathuba 3). Ngaphantsi kuka-1, kukho urhwebo lwexabiso olubuyisela u-1 / isixa - 1 kwisabelo siphelele.
- Isabelo kwisiphumo ngasinye = isabelo siphelele × (1 / amathuba aso) / isixa, ngoko ke isiphumo ngasinye sibuyisa isixa esifanayo.
- Ngokwenzeko, amaxabiso ayatshintsha, izabelo zinokulinganiselwa kwaye imithetho iyahluka phakathi kwababhejisi; ubhejo olungamkelwanga ngexabiso elibhaliweyo luphula urhwebo lwexabiso.
