Ohm's Law relates to the amount of current that will flow through a piece of conductor when a voltage is applied to it. If the resistance of the piece of conductor is R Ohms, then the current that will flow is
A. V = I/E B. I = V-R C. I = V/R D. I = R/V |
If the resistance of the piece of conductor is R Ohms, then the current that will flow is I = V/R.
C. I = V/R |
