WebFrom 2 to 4s, the 2A current increases the charge from 0 to 4C (coulombs) in 2 seconds. From 4 to 8, the -1A current decreases the charge from 4 to 0C in 4 seconds. That means it's 4 at T=4, and 0 at T=8. That's a segment of the line 8-T, as is easily verified by … WebThe current for that time is given as -1. So getting charge by integrating that gives -t, over the period 8 to 4. At the lower bound, it will be -4, so I thought the answer should be: integral upperbound - integral lowerbound and if upperbound is taken as an aribtrary point t, within the range, 4 it would be = -t - (-4) = 4 -t. find the derivative of ddx ln cos2xWebA rechargeable battery is plugged into a charger.
