為啥發電所的電功率不能用P=V2/R而是用P=I2R - Yahoo ... 但在參考書上有看到發電所的電功率(R不變)是用P=I2R，卻不能用P=V2/R，是因為後者所產生的能量會過大而導致電線熔掉的 ... 這只是P=IV與V=IR兩式演算而已
P=IV, P=I^2R, P=V^2/R, what are the distinctions between these ... I originally thought that these were just different variable equations to the same power generation, but just learned they are not. P=IV is for the ...
difference between P=IV and P=I^2R | Student Doctor Network Yes, but be careful when you use P=IV vs P=I^2R. When you have resistors in series, Vresistor is not equal to Vtotal as given. So you will have ...
I don't get the difference between P=IV, P=V^2/R and P=I^2R - The ... 2012年1月14日 - so P= I V = I IR = V/R V gives all the equations. ... basically the value of P is the same regardless of which equation u use. and whether you ...
P=i2r , v2/r , vi and v=ir? - Yahoo Answers 2009年1月1日 - This sounds like you are talking about reducing the losses in a transmission line of a power distribution system. If so, you seem to be confusing the ...
Drive the formula p=I2 R from p=iv by using ohm`s law ... 2008年3月3日 - Best Answer. KKu answered 7 years ago. Ohms law V=IR and P= IV then substitute V in eqn. for P i.e P=I (I R) =I²R. 0. 0. Comment ...
P=I2R and P=V2/R.Is P directly propiortional or inversely ... 2011年7月9日 - P = IV, with either voltage or current varying to test the relationship. So, P can be both directly and indirectly proportional to R, depending on the ...
Electrostatics: What power equations to use? - Physics Forums I was wondering what the different power equations are used for... P=IV, P=I2R, and P=V2/R I was solving for power loss and I noticed that ...
