25 ++ v=ri formula 552737-V ri formula
V=IxR, I=V/R, R=V/I It should be apparent that the formula works the other way too, that is;R Electric Energy The electric energy delivered by an electric current is the product of its power and time over which it flows — and therefore the product of voltage current time E = Pt = VIt This equation can also be combined with Ohm's law to produce variations E = VIt = I2Rt = `V_R= Ri` and `V_C=1/Cinti dt` Kirchhoff's voltage law says the total voltages must be zero So applying this law to a series RC circuit results in the equation `Ri1/Cinti dt=V` One way to solve this equation is to turn it into a differential equation, by differentiating throughout with respect to t `R(di)/(dt)i/C=0` Ohm S Law With Simple Explanation Examples V ri formula
