What is max current?

What is max current? Ampacity is defined as the maximum current, in amperes, that a conductor can carry continuously under the conditions of use without exceeding its temperature rating. Also described as current-carrying capacity. Electric current flowing through them causes voltage drop and power dissipation, which heats conductors. How do you find the maximum and […]

What does 50% lung capacity mean?

What does 50% lung capacity mean? Likewise, if your FEV1 is 50%, your lungs are able to handle only half as much air as they should. If your FEV1 is 33%, your lungs are able to handle even less—only a third as much. The lower your FEV1 percentage, the less air your lungs are able […]

How high can a balloon go?

How high can a balloon go? Because density is altered by altitude, the helium balloon can reach a height of 9,000 meters, or 29,537 feet. Anything higher than this altitude will cause the helium within the balloon to expand and the balloon to pop. What is the common unbalanced force acting on an object in […]
