'''Ohm's law''' says that in an [[electrical circuit]], the [[Electric current|current]] passing through a [[resistor]] between two points, is related to the [[voltage]] difference between the two points, and inversely related to the [[electrical resistance]] between the two points. This relation is shown in the following formula:
:<math>R = \frac VI</math>

=== Current ===
Current is how fast the charge is flowing. The higher the charge, the faster the current. Basically Current just electrons flowing in a circuit, and current is measure how fast the electrons go, The unit of the current is “ampere” , and usually can write it as “amps”. The letter “I” can represent as current.

=== Resistance ===
Resistance is something to resist the flow of the charge, to make sure they not flow too fast and break the circuit. In a circuit, light bulb can be a resistor, that electron through the light bulb, and the light bulb will light up, and if the resistance is high, then the light will be darker. The unit of resistance is “Ω”,  which is called omega, and pronounced “ohm”, it is the name of the inventor of Ohm’s law.<ref>{{Cite web|url=https://learn.sparkfun.com/tutorials/voltage-current-resistance-and-ohms-law|title=Voltage, Current, Resistance, and Ohm's Law|first=CTaylor|last=|date=|website=sparkfun|publisher=SparkFun Electronics|accessdate=10 June 2016}}</ref>

== How Current, Voltage, and Resistance are related==
Current, Voltage, and Resistance are related, which is call it “Ohm’s law”. Ohm defines the unit of resistance of “1 Ohm” as the resistance between two points in a conductor where the application of 1 volt will push 1 ampere, or 6.241×10^18 electrons.<ref>{{Cite web|url=http://www.allaboutcircuits.com/textbook/direct-current/chpt-2/voltage-current-resistance-relate/|title=How Voltage, Current, and Resistance Relate|first=|last=|date=6 June 2016|w(contracted; show full)
