Ohm's Law, Power, Applications in Real Life

Ohm's Law: states the during the current through a conductor between two points is directly proportional to the potential difference across two points. Basically, saying that current is inversely related to voltage and resistance. Ohm's are also the units for resistors. 
Equation: I=V/R
Power: the amount of energy consumed per unit time. The unit of power is amp.
Equation: P=W/t
The picture you see above is a prime example of Ohm's law because it shows what the product of Ohm's law is. The calculator you see above is powered by batteries, connected to those batteries are wires that are all connected onto a control panel that trigger different signs and signals to make different numbers and functions appear on the screen of the calculator. The battery source provides voltage, the amount of battery source that is required to run the calculator is the power used.
