9. Consider a series RLC circuit consisting of resistor R, inductor L, capacitor C and a voltage source applying alternating current according to 5(t) = V0 cos(wt). The solution to the equation PHYS 293 Problem Set #3 Chapter 2&3 dzq dq q L R = V dt2 + dt + C 0cos (out) is (20:) = (10(0)) 005(wt - 5) where V0 /L (10(0)) = l 2 2 00((w1C 00L) + R2) a. Determine expressions for voltage drop across each circuit element. b. Show that the current through the circuit is in phase with the voltage source when the source frequency a) = 000
