2.14 know and use the relationship between voltage, current and resistance: voltage = current × resistance V = I × R
Formula:
Voltage = current x resistance
This is just a rearrangement of the equation we had before, this is the more common version of it.
You would use this when you are told to find out one of them and only have the other two values.
