Voltage And Amps Explained

Electrical terms and definitions such as watts and volts are set by a system called si international system of units.

Voltage and amps explained. An intergovernmental international agency called bipm bureau international des poids et mesures sets terms and definitions for weights and measures under this system. So the watts would be. V voltage in volts. 1200 watts 120 volts 10 amps.

To put this in perspective a single lightning strike measures at approximately 20 000 amps. R resistance in ohms. The clie battery on our page is 3 7 v and 1200 mah. Watts volts x amps.

The water pressure would be the voltage. My blender uses 1200 watts on 120 volts. 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. Voltage can be compared to water pressure.

Voltage is measured in volts current is measured in amps and resistance is measured in ohms. This is called ohm s law. I current in amps. Volts represent the speed at which electrons pass a specific point within the closed circuit.

Watts volts amps and ohms defined. Remember that i m 1200 mah is the same as 12 ah and 800 mah is the same as 8 ah. Some experts may disagree but for my purposes amps are the way to go for thinking about electricity. How to calculate with watts amps volts and ohms if you want to do an electrical calculation involving voltage current resistance or power reference the formulae circle below.

My reasoning on this is simple. For example we can calculate the power in watts by referencing the yellow area in the circle. 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 is equivalent to the water pressure.

41 6 5 2 x 8. A neat analogy to help understand these terms is a system of plumbing pipes. Amps would be the volume of water flowing through the pipe. Amp an.

So with this analogy in mind the definitions below for amp volt and watt should be easier to understand. 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. Using ohm s law we can say. Now the orignial clie battery came with 800 mah and the volts is 5 2.

So the watts would be. 44 4 3 7 x 12. Voltage also abbreviated as volts or classified as v represents the difference in potential.
