A wire.
An open switch.
A resistor of resistance R.
A light bulb.
E) Totally different from any of the above.

3. Which circuit has a larger value of  = R∙C ?D6
Which circuit has a larger value of  = R∙C ? A B
Vin,out(t) t R A

5. Consider the low-pass filter at right
Consider the low-pass filter at right. When ω >> ω3dB, the phase shift of Vout with respect to Vin is approximately:
A) 0
B) π/4
-π/4
π/2
E) -π/2
Note: “+” means the output is behind
“-” means the output is ahead t
