Acomputer and monitor together have a power rating of 440 watts. if they use 110 volts, what current runs through the devices?

Power (in watts) = Voltage (in volts) x current ( In Amperes)

Putting the values in above equation we get:

440 watts = 110 volts X current ( In Amperes)

current ( In Amperes) = 440 watts/110 volts

= 4 Amperes

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
