Ohmmm....Ω

We use power in everything we do these days and rely heavily on it for simple daily tasks. For example when you wake up from your ALARM in the morning you turn on your LIGHTS and head to the kitchen and open up your REFRIGERATOR and use your TOASTER to make food. As we need electricity in many of our activities many people dont know the dynamics of electricity.  A predominately used equation in physics is the Ohm's law equation which is V=I x R. In words, the electric potential difference between two points on a circuit (V) is equivalent to the product of the current between those two points (I) and the total resistance of all electrical devices present between those two points (R). So you can calculate the voltage required for many of these electrical devices if you really cared that much.
