WebSep 12, 2024 · Thus it makes sense to have lower current during transmission. This is done by using step-up transformers to increase the voltage. Since transformer cannot add power, the current will automatically come down. For ex - assume that wire has a resistance of 1 ohm and you want to deliver 100 watts of continuous power at the other end.

WebAnswer (1 of 9): What you heard has a ring of truth to it in the sense that there is proportionality relationship. Power is proportional to the voltage square. To sort all this out only two relationship are needed: P=IV and V=IR Those two equations and a bit of algebra are all that is needed to... WebOct 10, 2024 · In power transmission lines current is kept low and voltage is kept high to reduce the power loss. This is because P = I 2 R and P = V I. In order to reduce power loss we have to reduce I since P = I 2 R ( R is obviously a constant). And to reduce I we have to increase V because P needs to be a constant ( P = V I ). Here's my question.
