Sebuah
generator DC kompound pangjang memberikan arus 100A pada teganganterminal 500V.
Jika tahanan medan motor 0,02 ohm dan tahapan mdan seri 0,04 ohm car tegangan
EMF yang di bangitkan jika jatuh tegangan setiap sikat 1V,reaksi jangkar di
abaikan <o:p></o:p></div>

<div class="MsoNormal" style="line-height: normal; margin-left: 36.0pt; text-align: justify;">
Jatuh
tegangan  pada medan seri = Ia
x Rf<o:p></o:p></div>
<div class="MsoNormal" style="line-height: normal; margin-left: 36.0pt; text-align: justify;">
                                                      100 x 0,04 =
4 V<o:p></o:p></div>
<div class="MsoNormal" style="line-height: normal; margin-left: 36.0pt; text-align: justify;">
Jatuh
tegangan pada medan motor = Ia x Rm motor<o:p></o:p></div>
<div class="MsoNormal" style="line-height: normal; margin-left: 36.0pt; text-align: justify;">
                                                        100 x 0,02 = 2V<o:p></o:p></div>
<div class="MsoNormal" style="line-height: normal; margin-left: 36.0pt; text-align: justify;">
Vemf
= Vt – (Ia x Rs) – (Ia x Rm motor) = 500v – 4v – 2v
= 494 V<o:p></o:p></div>
<div class="MsoNormal" style="line-height: normal; margin-left: 36.0pt; text-align: justify;">
