Question

Answer:

Please help! Electrical series circuits never make sence to me. I included the answer so that you can check your work.
Hope that helps.

19. An electrical series circuit contains a resistor with a resistance of R- 20 ohms, a capacitor with a capacitance of C 0.01 farads, and an inductor with an inductance of L 1 henry. The initial current in the circuit is 0 amperes. A variable voltage of E(t) 120 sin volts of is applied to the circuit for the first 27t seconds. At 2 π seconds, the voltage is switched to a constant 24 volts Model this system with an initial value differential equation problem, using current, i, as the dependent variable, if the equation LRi()dt provides a reasonable model of the system a. di dt E(t) 0 Find the form of the equation that gives the current in the system at any time. Express the equation in terms of the functions that appear in the solution, but do NOT find the coefficients of these functions. b.
