Learning Goal:
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 , R1 = 52.0 kN , R2 = 23.0
kN , R3 = 38.0 kN , 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.
