$2)$ When the projection of the phasor $\backslash ($ E$\_\{$A$\}\backslash )$ onto $\backslash ($ V$\_\{\backslash$varphi$\}\backslash )$ is shorter than $\backslash ($ V$\_\{9\}\backslash )$ itself, a synchronous generator has a leading current and supplies reactive power

$6-$ In the synchronous generator circuit the voltage regulation for leading power factor is positive.

e$-$ The frequency of the oncoming generator must be slightly greater than the frequency of the running system.

$-$ In the synchronous motor circuit, an increase in field current decreases the magnitude of $\backslash (\backslash$mathrm$\{$E$\}\_\{\backslash$mathrm$\{$A$\}\}\backslash )$ but increase the real power supplied to the motor. $\backslash (\backslash$quadvee $\backslash$varphi $\backslash )$

e$-$ When the projection of the phasor $\backslash (\backslash$mathrm$\{$E$\}\_\{$A$\}\backslash )$ onto $\backslash (\backslash$mathrm$\{$V$\}\_\{\backslash$varphi$\}\backslash )$ is shorter than $\backslash (\backslash$mathrm$\{$V$\}\_\{\backslash$varphi$\}\backslash )$ itself, a synchronous motor has a leading current and supplies reactive power.

ff In de machine circuit when the coil is located under the pole the brushes commutate the segments.

$15-$ Like a shunt DC motor the cumulatively compounded DC motor does not over speed at no load.

b$.$ The compensating winding in a de motor cancel the armature reaction affect but decrease its reference speed.

$+$ In de machine circuit the semi$-$circular conductors of commutator rotate with its shaft.

T$)$ The torque$-$speed characteristics of a series DC motor is a straight line with positive slope.
