Voltage And Amperage Explained

The voltage is equivalent to the water pressure the current is equivalent to the flow rate and the resistance is like the pipe size.

Voltage and amperage explained. So with this analogy in mind the definitions below for amp volt and watt should be easier to understand. Voltage can be compared to water pressure. Because the resistance is greater and the voltage is the same this gives us a current value of 0 5 amps. The voltage v in volts v is equal to the current i in amps a times the resistance r in ohms ω.

The water pressure would be the voltage. 1200 watts 120 volts 10 amps. 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. Amp an.

It says that the current is equal to the voltage divided by the resistance or i v r. Yoyo on november 05 2018. Electrical terms and definitions such as watts and volts are set by a system called si international system of units. The voltage v in volts v is equal to the power p in watts w divided by the current i in amps a.

The voltage v in volts v is equal to the square root of the power p in watts w times the resistance r in ohms ω. Amps vs volts. I don t care about small electrical quiz i what one question answered what gauge wire is needed to hook up a welder rated at 230 volts 220 amps as far as i got as it is with electricity is this high a amperage will kill you. Now we can see that if we know two of the values for ohm s law we can solve for the third.

This is known as ohm s law. An intergovernmental international agency called bipm bureau international des poids et mesures sets terms and definitions for weights and measures under this system. Amperes amps and volts are the basic concepts that one learns when studying electricity in physics. My blender uses 1200 watts on 120 volts.

There is a basic equation in electrical engineering that states how the three terms relate. Some experts may disagree but for my purposes amps are the way to go for thinking about electricity. Aamir on january 17 2019. While current in electricity is measured in amps voltage describes potential difference across terminals or bodies.

So the current is lower in the tank with higher resistance. Amps increase and decrease in a linear fashion straight line not an exponential curved line meaning they are pretty predictable and easy to anticipate with mental math. To put this in perspective a single lightning strike measures at approximately 20 000 amps. Voltage also abbreviated as volts or classified as v represents the difference in potential.

Thanks it was interesting. My reasoning on this is simple.
