[Amateur-SIG] EXTRA CLASS EXAM BRAINTEASERS

[Bill Serra]

Hi Gang,

Just FYI, here are some of the  "trick" questions Todd and I have 
experienced while on the way thru the EXTRA class study materials.

PS:  I feel like I am almost ready to sit for the test. Does anyone know 
of locally conducted tests during the week?

I plan to check out DARA - I think they still hold exams during the week.



  [27] In rectangular coordinates, what is the admittance of a circuit
that has an impedance of 240 ohms at 36.9 degrees?  [E5E19(2002)]
	3.33 x 10(-3) + j2.50 x 10(-3) siemens
	192 + j144 siemens
	3.33 x 10(-3) - j2.50 x 10(-3) siemens
	3.33 - j2.50 siemens



  In polar coordinates, what is the impedance of a circuit that has an
admittance of 7.09 millisiemens at 45 degrees?  [E5E17(2002)]
	5.03 x 10(-5) ohms, /__45_degrees__
	19,900 ohms, /__-45_degrees__
	141 ohms, /__45_degrees__
	141 ohms, /__-45_degrees__

  [21] In rectangular coordinates, what is the impedance of a circuit
that has an admittance of 5 millisiemens at -30 degrees?  [E5E18(2002)]
	173 + j100 ohms
	200 - j100 ohms
	200 + j100 ohms
	173 - j100 ohms
