Definition of amps, volts, watts, resistance, current, ohms, electrical phases. We include basic formulas relating amps, volts, resistance, watts, and we explain what these electrical terms mean in practical applications such as for building or appliance electrical power, electrical wiring, and basic troubleshooting. ten-amp 240V electrical service is capable of delivering, speaking roughly, twice the energy to the end-user than a ten-amp 120V electrical service. So volts is a measure of the strength of an electrical source at a given current or amperage level.
A changing climate isn't inherently bad, and commentators who are sceptical about the risks posed by global warming often point to the benefits that higher temperatures could bring â such as longer growing seasons in cool countries and more efficient shipping routes through an ice-free Arctic.
The natural greenhouse effect has been keeping the earth warm for millions of years, allowing life to thrive on this planet. The enhanced or accelerated greenhouse effect, which is what is happening now, is causing global warming and may mean the end of life on earth if we can't slow or stop it.o this  natural greenhouse effect is very useful.    The gases that keep the earth warm are called greenhouse  gases. The most important gas, causing about 75% of the  natural greenhouse effect, is water vapor.
