- The current through a given circuit element is given by i(t) = 2 e−t A. Find the net charge that passes through the element in the interval from t = 0 to t = ∞ [Hint:Current is the rate of flow of charge. Thus, to find charge, we must integrate current with respectto time.]arrow_forwardIn the figure attached, let E=60 V, R1=2 ohms, R2= 3 ohms, L1= 1 H, L2= 1 H. Determine the currents in the circuit at time t >= 0 if the initial currents are equal to zero.arrow_forwardQ1 For the figure shown below answer allthe following 1.
