LED實驗室(基礎入門) LED電流限制電阻計算法 ... 因此理論值為(14.4-9.5)÷0.02(電流20ma)=245Ω 。 ... 功率全部消耗在限流電阻,這樣壓差太大,限流電阻會過熱,易導致LED燒毀。
P=IV和V=IR(電與生活、電功率)(頁1) - 國中理化討論區- FunLearn ... 從電功率的公式來看 P=IV I跟V成反比可是從歐姆定律V=IR來看I跟V成 ... (2)輸送線 符合歐姆定律和輸送線上電能損失的功率則要一起看,意思是說 ...
為何提高電壓可使電流降低?會和V=IR衝突嗎- Yahoo!奇摩知識+ 我們補習班老師問我們一個問題:台電輸電時,升高電壓,則電流下降可用P=IV=I(平方) R=V(平方)/R用 ...
欧姆定律- 维基百科,自由的百科全书 假設施加週期性電壓或週期性電流於含有電抗元件的電路,則電壓與電流之間的關係 式變成微分方程式。因為歐姆定律的 ...
【問題】遵守V=IR 不等於遵守歐姆定律? - 深藍論壇 本來就沒有全部的物體都會遵守V=IR呀 .... 可以用V=IR 這個公式的物體並不一定會 滿足歐姆定律?
Ohm's law - Wikipedia, the free encyclopedia where I is the current through the conductor in units of amperes, V is the potential difference measured across the conductor in units of volts, and R is the ...
Ohm - Wikipedia, the free encyclopedia The ohm (symbol: Ω) is the SI derived unit of electrical resistance, named after German physicist Georg Simon Ohm. Although several empirically derived standard units for expressing electrical resistance were developed in connection with early telegraphy
Ohm's law - Wikipedia, the free encyclopedia where I is the current through the conductor in units of amperes, V is the potential difference measured across the conductor in units of volts, and R is the resistance of the conductor in units of ohms. More specifically, Ohm's law states that the R in t
