ตัวต้านทานการ A resistor restricts the flow of current, 1 resistor (n.) ไหลของกระแส for example to limit the current passing through an LED. ไฟฟ้า A rheostat (a type of variable resistor) variable resistor ตั ว ต้ า นทานปรั บ 2 (n.) is usually used to control current like ค่าได้ adjusting lamp brightness. 3 capacitor (n.)
4 polarized capacitor (n.) 5 variable capacitor (n.) 6 diode (n.) LED light 7 emitting diode (n.)
A capacitor stores electric charge. A capacitor is used with a resistor in a ตัวเก็บประจุ timing circuit. It can also be used as a filter, to block DC signals but pass AC signals. Electrolytic capacitor is one type of ตัวเก็บประจุแบบ polarized capacitors; one terminal must always have positive potential มีขั้ว with respect to the other. ตัวเก็บประจุปรับ A variable capacitor is used in a radio tuner. ค่าได้ A diode is a device which only allows ไดโอด current to flow in one direction. A transducer which converts electrical ไดโอดเปล่งแสง energy to light is called a light emitting Diode.
