Ohms Law


Ohm's law is named after a German Physicist Gerog Simon Ohm.  Ohm's law shows a direct relationship between the voltage applied to an object and the resulting current.  Its used in finding resistance and the formula that goes with the law is V=IR which is electric current = voltage / resistance. Ohm is the unit of resistance. Electric Power is a complete electric circuit that represents rate at which energy is converted from the electrical energy of moving charges to another form.  Power equals the rate at which energy is utilized.  Watts is the units of power.  The equation is P = VI (Power = energy converted / time = voltage x charge / time = voltage x charge / time = current x voltage).  Where Watts = Joules / second.
This not so great quality picture I took when I went to las vegas. It is of the roller coaster New York New York. Without electricity none of this would have been running.
