Ubushyuhe bwa PTCKu binyabiziga byamashanyarazi gusa, bateri ni bateri yumubyigano mwinshi kandi ubushuhe bwamashanyarazi muri rusange bwatoranijwe kuba voltage nyinshi kuko voltage nini kandi ingufu zimwe zamashanyarazi zirashobora guhinduka mubushyuhe kenshi.
Ukurikije uko icyuma gishyushya amashanyarazi gikora nacyo gishobora kugabanywamo ibishyushya umwuka (Ubushyuhe bwo mu kirere) mu buryo butaziguye n'izishyushya umwuka mu buryo butaziguye no gushyushya amazi.Ubushyuhe butaziguye bwo mu kirere bushingiye ku ihame rimwe nogosha amashanyarazi, mugihe ubwoko bwo gushyushya amazi bwegereye uburyo bwo gushyushya.Iki gihe turerekana kandi twerekana amashanyarazi ashyushye.
