```How to read the value of a resistor?
22 ohm
470 x 0.1

1k resistor:
or
What resistor value is
(a)
(b)
Recap:
Vin
R2
Voltage divider
Vout = I R1
R1
= Vin
R1
R1 + R2
Thevenin’s equivalent
Rth
Vth
How to avoid voltage droop?
To appear in Quiz
Method 1: apply kirchoff’s law
Method 2: use Rth = Vth/Is
Is is the short circuit current.
When we short the output to ground,
what is the current through R4?
Q = CV
I = C dV/dt
Zc = 1/jZC
ZL = jZL
ZR = R
I
