PPLICATIONS 四端點量測技術可以用來準確地測量點2與點3之間的電阻。
Test and measuring equipment 測量電阻
電阻計是測量電阻的儀器。由於探針電阻和接觸電阻會造成電壓降,簡單電阻器不能準確地測量低電阻。高準確度測量工作必須使用四端點測量技術(
four-terminal measurement technology)。
Industrial and medical electronics
The MPM- Metal film Resistor are made by depositing special treated
metal film onto ceramic core in ultra high vacuum. Both ends
of the core are plated with precious metal to ensure low noise
and small temperature coefficient. MPM Resistor are widely applied in
high fidelity stereo, electronic calculators, computers, testing instruments,
meters, auto controlled equipment, military devices and aerospace equipment.

分流電阻: Resistance = R1+R2/2 ()在總的電流(I)不變的情況下,電路上並聯一個分路將能起到分流作用,經過的電流將會分流通過,使原本通過該電路的電流變小。當原本只流經一道的電流太大時, 可以分開電流通道,分擔大的電流,選擇分流電阻的阻值越小,分流的作用越明顯。有如有二道分開的入口通道分開拥擠的人群。它最大的考慮點是你將要開多大的電流通道才適合。取決於你要選用多大的電流值(A)。如圖是典型的分流電路(R1//R2)
