2 Answers 2. The gate-source threshold voltage is the voltage that is required to conduct (usually) 100 uA of current into the drain. Different MOSFETs have different definitions and some devices define the threshold voltage at up to 1 mA drain current.
The Earthâs Centre is 1000 Degrees Hotter than Previously Thought. Scientists have determined the temperature near the Earthâs centre to be 6000 degrees Celsius, 1000 degrees hotter than in a previous experiment run 20 years ago.he layers of the Earth and their temperatures: crust, upper and lower mantle, outer core and solid iron core. Credit ESRF. The Earthâs core consists mainly of a sphere of liquid iron at temperatures above 4000 degrees and pressures of more than 1.3 million atmospheres.
Earth sits much closer to the sun than Mars does and is thus more intensely subjected to the sunâs formidable power. Not only does the sun generate temperatures on its surface upwards of more than 10,000Â° F (5,538Â° C), but its core temperature is over 27 million degrees Fahrenheit (15 million degrees Celsius)!
