Ohm's law

Not only did Mr Ohm work on resistance and give his name to the amount of electrical resistance materials have but he also created Ohm's law which is:

`V=IR`

Ohm's law Mnemonic picture.

           1. Resistance say Oh my (Ohm's) he is heavy.
    Resistance `(R)` is measured in Ohm's `(Omega)`
     
  2. Currently I'm not travelling very fast.
    It is the speed of the electrons through the cable.
    Current `(I)` is measured in Amps (remember C.I.A.)
     
  3. Voltage comes from volting from a height.
    Voltage `(V)` is measured in volts
