   Answers could be in retangular form or polar. In polar form needs the
    phase angle.

| 1278.1 | those are BIG capacitors! | GUESS::DERAMO | Dan D'Eramo | Mon Aug 06 1990 16:58 | 3 | 
| Is this a homework problem? :-) Dan | |||||
| 1278.2 | HPSTEK::XIA | In my beginning is my end. | Mon Aug 06 1990 23:42 | 5 | |
|     re .0,
    
    3kF and 5kF capacitors???!!!  It must be a home work problem. :-)

| 1278.3 | frequency to be calculated ? | EAGLE1::BEST | R D Best, sys arch, I/O | Tue Aug 07 1990 11:20 | 4 | 
| I think maybe the numbers supplied next to capacitors and inductors are the equivalent impedances at a given frequency. Notice that the frequency of the source is not given; apparently the reader must back-calculate the frequency and then proceed from there. | |||||
| 1278.4 | XL and XC are Given | TRAM::GLEN | Tue Aug 07 1990 16:05 | 5 | |

    The frequency doens't need to be calculated. Cause the components of C
    and L are your XC and XL.
