Relation Between Volt And Ampere
One volt is defined as the difference in electric potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points the volt is named after the italian physicist alessandro volta.
Relation between volt and ampere. The following simple illustration works well for non electrical plumbers who require basic electrical qualifications t. Voltage vs amp hours. For a given voltage the more power an electrical circuit consumes the more current flows through it. Let s say you have a system with a 6 volt light bulb hooked up to a 6 volt battery.
Watts would be the power volts x amps the water could provide think back to the old days when water was used to power mills. Now they re producing just 3 6 volts but 6 0 amp hours. The relation between watt and volt is direct. Voltages are generally expressed in volts with prefixes used to denote sub multiples of the voltage such as microvolts μv 10 6 v millivolts mv 10 3 v or kilovolts kv 10 3 v.
You cannot convert watts to amps since watts are power and amps are coulombs per second like converting gallons to miles. However if you have at least least two of the following three. Since watts are amps multiplied by volts there is a simple relationship. Amp hours are units of current storage capacity.
This implies that change in the value of watt will reflect in the change in the value of volt. So with this analogy in mind the definitions below for amp volt and watt should be easier to understand. How to convert watts to amps or amps to watts or volts to watts. Amps would be the volume of water flowing through the pipe.
Amps volts or watts then the missing one can be calculated. The water pressure would be the voltage. Using the equation i p v we can calculate how much current in amps would be required to get 100 watts out of this 6 volt bulb. Amp an.
The below explanation is one of the simplest ways of understanding how fundamental direct current d c. 1 watt 1 ampere 1 volt 1 volt frac 1 watt 1 ampere where watt is the measure of power. The power output of the light bulb is 100 watts. In the measurement of electricity amps are a unit of electrical current.
You know that p 100 w and v 6 v. Each cell carries 3 6 volts and 2 0 amp hours. Since they re in a series we get 10 8 volts or 12v when fully charged but still just the 2 0 amp hours. Volts are the base unit used to measure voltage.
In physics the relation between watt and volt can be written as. Voltage is measured in volts with one volt being defined as the electrical pressure required to force an electrical current of one ampere through a resistance of one ohm.
