Extracted text: 2. The total charge entering a terminal is given by q = (10 – 10e-2+) mC. Calculate the current at 0.5 s %3D 3. The voltage v across a device and the current į through it are v(t) = 5 cos 2t V and i(t) = 10(1 – e-0.5t) A. Calculate the power consumed by the device at t = 1s. 4. The charge entering a certain element is shown below. Find the current at (a) t =1 sec and (b) t = 5 sec
