To analyze an RC circuit to determine the initial voltage across a capacitor, the time constant, and the expression for the natural response of the capacitor voltage, and then to find other circuit quantities such as current, voltage, power, or energy. Part A - Find the initial voltage across the capacitor For the given circuit (Figure 1), the switch has been at position a for a long time. Find the initial voltage across the capacitor. Assume that V, = 10.0 V , R = 52.0 kn , R2 = 2 kn , R3 = 38.0 k2 , and C = 84.0 µF . The natural response of an RC circuit is the response of the capacitor voltage to the sudden removal of a DC source. When this occurs, the capacitor releases its stored energy. Express your answer to three significant figures and include the appropriate units. • View Available Hint(s) Tempjetes Symbols undo rego Teset keyboard shortcuts Help v(0 ) = v(0* ) = Value Units Submit Part B - Find the time constant after t= 0 The diagram (Figure 2) represents the original circuit the instant after the switch moves.
