After troubleshooting a series RL circuit, you check the resistance of the inductor and it is around 40 ohms. What conclusion does this bring you to?

A) Since the inductor's voltage was nearly zero, the inductor is probably okay so the resistor must be shorted.
B) Since the inductor's voltage was nearly zero, the inductor is probably okay, so the resistor must be open.
C) Since the inductor's voltage was nearly zero, you are sure the windings have shorted.
D) not enough information

Question 2

It is suspected that a high pass filter's cutoff frequency has changed. What pieces of test equipment could be used to check it out?

A) an oscilloscope and a square wave generator B) voltmeter and a sine wave generator
C) either A or B D) none of the above
