The oscillating current in an electrical circuit is as follows, where I is measured in amperes and t is measured in seconds. I = 3 sin(1202rt) + cos(602rt) Find the average current for each time interval. (Round your answers to three decimal places.) 1 a Osts_ () 60 l:lx amps 1 b 051:5 () 240 l:lx amps 1 c Citi () 30
