Unformatted text preview: 8. At a time t = 0 , the terminals of a 200k Ω resistor are connected to the terminals of a 3 µ F capacitor carrying a 12 µ C charge on its positive side. Find the expression for the voltage V across the capacitor as a function of time. 9. Solve for the current phasor through the four-ohm resistor in the AC circuit shown. 10. A solenoid oriented along the x-axis as shown has 100 turns and an overall length of 10cm . If the current through its coils is ½ A , find the force vector on a particle carrying a charge q that enters the interior region of the solenoid with an initial velocity vector of v ѐ = (-7x ˆ +2y ˆ – z ˆ )m/s . Express your answer in terms of q and µ ₀ . 2k Ω 10k Ω 30V 4k Ω 22V A D B C 110V 8 cos (2000t)V 4 Ω ⅛ mF I x ˆ...
