W = E x I

W = I

^{2}x R

W = E

^{2}/ R

I = W / E

I = (W / R)

E = W / I

E = I x R

R = E

^{2}/ W

R = W / I

R = E ÷ I

**What is Ohm's Law:**

Ohm's Law is made from 3

The difference between the pressure of water in the tank and the water that comes out of a pipe connected at the bottom leading to a faucet is determined by the size of the pipe and the size of the outlet of the faucet. This difference of pressure between the two can be thought of as potential Voltage.

All three of these: voltage, current and resistance directly interact in Ohm's law.

Change any two of them and you effect the third.

**mathematical equations**that shows the**relationship**between electric**voltage**,**current**and**resistance**.**What is voltage?**An anology would be a huge water tank filled with thousands of gallons of water high on a hill.The difference between the pressure of water in the tank and the water that comes out of a pipe connected at the bottom leading to a faucet is determined by the size of the pipe and the size of the outlet of the faucet. This difference of pressure between the two can be thought of as potential Voltage.

**What is current?**An analogy would be the amount of flow determined by the pressure (voltage) of the water thru the pipes leading to a faucet. The term current refers to the quantity, volume or intensity of electrical flow, as opposed to voltage, which refers to the force or "pressure" causing the current flow.**What is resistance?**An analogy would be the size of the water pipes and the size of the faucet. The larger the pipe and the faucet (less resistance), the more water that comes out! The smaller the pipe and faucet, (more resistance), the less water that comes out! This can be thought of as resistance to the flow of the water current.All three of these: voltage, current and resistance directly interact in Ohm's law.

Change any two of them and you effect the third.

*Info: Ohm's Law was named after Bavarian mathematician and physicist Georg Ohm*.
Ohm's Law can be stated as

same principle.

In the following equations,

**mathematical equations**, all derived from thesame principle.

In the following equations,

**V**is voltage measured in**volts (the size of the water tank),****I**is current measured in**amperes (related to the pressure (Voltage) of water thru the pipes and faucet)**and**R**is resistance measured in**ohms****as related to the size of the pipes and faucet:**

**V**=

**I x R (Voltage = Current multiplied by Resistance)**

**R**=

**V / I (Resistance = Voltage divided by Current)**

**I**=

**V / R (Current = Voltage Divided by Resistance)**

**Ohm's Law defines the relationships between (P) power, (E) voltage, (I) current, and (R) resistance. One ohm is the resistance value through which one volt will maintain a current of one ampere.**

( I ) Current is what flows on a wire or conductor like water flowing down a river. Current flows from negative to positive on the surface of a conductor. Current is measured in (A) amperes or amps.

( E ) Voltage is the difference in electrical potential between two points in a circuit. It's the push or pressure behind current flow through a circuit, and is measured in (V) volts.

( R ) Resistance determines how much current will flow through a component. Resistors are used to control voltage and current levels. A very high resistance allows a small amount of current to flow. A very low resistance allows a large amount of current to flow. Resistance is measured in ohms.

( P ) Power is the amount of current times the voltage level at a given point measured in wattage or watts.
