Practical things about Diodes

In this topic we shall see about the practical things about diode. When we use diode in different practical circuits we always require to note these points. So I recommend you to perform the given steps in this topic as a part of practical experimentation. Aim: To study the basic concepts of PN junction diode. […]

Practical things about Diodes & LEDs

About Diodes Diode and LEDs (Light Emitting Diodes) are semiconductor devices. They are made up of Silicon and other special elements. The symbol of diode and LED are given below: A diode has two terminals ANODE and CATHODE. The diode or LED conducts current only in one direction i.e. from ANODE to CATHODE. Hence it […]

Capacitor blocks DC but passes AC

Let us see how to prove that capacitor blocks DC but passes AC using a practical circuit. For that we shall perform an experiment as explained below: Aim: To study the behavior of capacitor to AC/DC current through it. Apparatus: Battery – 6/12V, C – 1000mF, 25V rating, DMM – high internal resistance DMM like […]

Charging & Discharging of Capacitor

Capacitor is a device to store electric energy in the form of PD across its terminals. It consists of two metallic plates having area (A) separated by small distance (d). The medium between the two plates is called dielectric medium or dielectric. If the dielectric medium is paper, it is called paper capacitor, if the […]

Understanding Batteries

Batteries are the best DC voltage sources. Batteries are portable and very useful for small circuits power supplies. A battery or cell has two terminals, positive (+) and negative (-). It provides DC voltage. Every cell or battery has fixed current rating indicated as Ah (Ampere hour). Batteries in Series When number of batteries are […]
