Celexa: t1/2 = 37 hrs. 40 mg decreases to what after 1 day? How much (in general) after 1 day:
Celexa: What if you keep taking them every day? D0 = 40 mg .64/day 100 mg 50 mg 0 1 2 3 4 5 DAYS
Celexa: some math: what’s the maximum dose you ever get? Equilibrium: Day’s loss = next dose
RC circuits again! Time constant: Charging: Discharging:
DISCHARGE Example: R = 2.20 k and C = 150 μF – charged up to 15 V. How long for VC to fall to 10V when the switch is closed? when switch closed
CHARGE Example: How long will it take to charge the Cap up to 10 V? when switch closed
The neon light bulb: off on (about 60 V)
Relaxation oscillator: 555 demo
REVIEW: What are the voltages across, and charges of, each Cap? + more space …
