Explain two uses each of transistor & capacitor? |
|
Answer» Transistor 1. Transistor plays a vital role as a semi-conductor in many electronic gadgets. It is used as an amplifier switch in many equipment. 2. Due to its small size, it is used in place of electron tubes in modern electric gadgets. For example: the vacuum tubes from the old radios have been replaced by transistors, hence making them smaller in size. Capacitor 1. Capacitor stores and regulates the fluctuation in current and transfers it to the electric circuit. 2. Capacitor is used to temporarily store electric energy. There are two electric conductors in a capacitor. These are separated by an insulator. Glass, vacuum air, paper or plastics may be used as an insulator in the capacitor. 3. In an electric connection or circuit, capacitor is used to block direct current in order to allow flow of alternating current. |
