I would like to introduce again my assistant Krystal. Fresh out of a party, she'll do her best to explain the lab conducted here. Again, sit back and let her taking you for the ultimate in physics pleasure. Voltage is measured in volts. Current is measured in amps.
Resistance is measured in ohms.
Ohms law basically covers the relationship between voltage and current along an ideal conductor. One of the properties of this equation is that it is linear, and in the same way, we can use Ohm's law only on linear circuits and such. Now, as for practical uses for Ohm's Law, there is one really major one. Ohm's law can be used to solve simple circuits. This particular law deals with the conservation of electrical charge.
