Unit 3 Day 11: RC Circuits • RC Circuit Introduction • RC Circuit Analysis • RC Time constant • Charging and discharging of an RC Circuit
RC Circuits • Circuits that contain both resistance and capacitance are called RC Circuits • RC Circuits are used in timing circuits, camera flashes, pacemakers • RC Circuit analysis is not just interested in steady state voltage and currents but rather how the circuit behaves over time
RC Circuit Transient Analysis • is a time constant • The voltage across the capacitor reaches 98% of the battery EMF in 4 • The transient response of the circuit is over in approximately 4 - 5
Discharging RC Circuit • Suppose a capacitor is charged to a voltage V0, and then connected across a resistor as shown below.
