QUESTION 10/VRAAG 10<br />
10.1 As the capacitor charges the direct current decreases and eventually<br />
becomes zero when the capacitor is fully charged. <br />
Soos wat die kapasitor laai, verminder die direkte stroom en word<br />
uiteindelik nul wanneer die kapasitor ten volle gelaai is. <br />
