While conducting a secondary wire resistance test, Technician A states that wire resistance
should be approximately 12,000 ohms per
foot. Technician B says that resistance should
be about 50k ohms (50,000 ohms) maximum
for long spark plug cables. Who is right?
(A) A only.
(B) B only.
(C) Both A and B.
(D) Neither A nor B.

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 3.00 ms . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?
