Current in a RC Circuit The equation governing the amount of current I (in amperes) after time t (in microseconds) in a single RC circuit consisting of a resistance R (in ohms), a capacitance C (in microfarads), and an electromotive force E (in volts) is E(RC) I = R (a) If E = 120 volts, R = 2000 ohms, and C = 1.0 micro- farad, how much current I is flowing initially (t = 0)? After 1000 microseconds? After 3000 microseconds? (b) What is the maximum current? (c) Graph the function I = I1(t), measuring I along the y-axis and t along the x-axis. (d) If E = 120 volts, R = 1000 ohms, and C = 2.0 micro- farads, how much current I2 is flowing initially? After 1000 microseconds? After 3000 microseconds? (e) What is the maximum current? (f) Graph the function I = I2(t) on the same coordinate axes as 1(1). %3D
