How To Understand Voltage And Amps
How To Understand Voltage And Amps. V 12 volts / i 14.1 amps = r 0.85 ω ohms. Unlike voltage, which represents physical power, watts refer to electrical power.

It turns out there is a simple relationship: Amps measure the amount of electricity being used. Most manufacturers will give you power ratings in watts.
If You Look At The Electric Wheel Below, You Can Se We Could Have Used V² / P = R.
The voltage is equivalent to the water pressure, the current is equivalent to the flow rate, and the resistance is like the pipe size. Amps measure the amount of electricity being used. Amperage (a)is the measure of the amount of electricity sent through a wire or circuit, also known as electric.
Pressure Divided By Resistance Equals Flow Rate.
The term “watts” refers to the power of your electrical current. Voltage (v) current (i) resistance (r) power (p) each of these quantities are measured using different units: Current is measured in amperage or “amps” for short.
They Are Closely Related Terms And Can Be A Bit Difficult To Understand.
V² ( 12 x 12) / p 170 watts = r 0.85 ω ohms. Watts is watts is watts. Why are there so many.
Amps Are Simply The Amount Of Electricity Used By The Item.
In this example volts would represent your water pressure. 120/240 means that the motor can be wired to operate on 120v or 240v. Voltage, on the other hand, is the unit of current.
Current Is Measured In Amperes (Usually Just Referred To As Amps).
Voltage is measured in volts, current is measured in amps and resistance is measured in ohms. An ampere is defined as 6.241*10^18 electrons (1 coulomb) per second passing through a point in a circuit. Specifically, voltage is the measure of electric potential difference between two points whereas ampere is the measure of electric current.
