The current through an element is shown in Fig. 1.26. Determine the total charge that passed through the 1.9 element at: (a)t 1 s (b) t= 3 s (c) t 5 s i (A) A 10 5. 2. 3 5 1(s)

Determine the current flowing through an element if the charge flow is given by 1.2 (a) q(t) = (3t + 8) mC (b) q(t) = (8t² + 4t – 2) C - (c) q(t) = (3e¬ – 5e¯ª) nC = 10 sin 120 t pC (d) q(t) = -4t (e) q(t) = 20e¯“ cos 50tµC

For an electrical component, the formulas for charge and voltage are given below. A is 9 coulombs, B is 12 seconds, C is 3 volts, and D is 24 seconds. Give the current of this component at t1 = 8 sec. You must round your answer to the nearest thousandth and give your answer as an integer followed by the appropriate metric prefix and the letter that represents the units of current.
