subscript incorrect | XL = 2 pi fL |
|
2.7 |
equation 2.6 |
sub and super scripts are incorrect | Z = SQRT (R2 + (XL - Xc)2 ) |
|
2.7 |
equation 2.7 |
sub and super scripts are incorrect | Z = SQRT (R2 + (XL)2 ) |
|
2.7 |
equation 2.8 |
sub and super scripts are incorrect | Z = SQRT (R2 + (Xc)2 ) |
