### Answer for Ch. 33, 31E

8.66 milli-ohm

### Answer for Ch. 33, 33P

*t* = (*L/R*) *ln(2)*

### Answer for Ch. 33, 34P

For *N=5*, *q* = 5.85 microC.

For *N=10*, *q* = 5.52 microC.

For *N=100*, *q* = 1.93 microC.

### Answer for Ch. 33, 36P

Substitute this derivative and the one from the hint into Eq. 33.20 to find the
final expression.

b) Beta is 11.4 rad/sec and omega is 176 rad/sec.
When beta is much smaller than the omega, the fractional shift introduced by loss
can be approximated by -(beta/omega)^{2}/2.
Thus the fractional shift in frequency is 0.2%.
