20 Lip-smacking Places For Street Food In Kalkata

Kalkata the Cultural Capital of India is a heaven for foodies and especially for people with a sweet tooth. Bengali sweets are famous and certainly needs no introduction, however; the spicy, tangy and absolutely mouth-watering dishes that Kolkata has to offer will leave you undecided on whether you like the spicy Bengali cuisine more or the melting flavors…

What is a diode?

A diode is a semiconductor device that essentially acts as a one-way switch for current. It allows current to flow easily in one direction, but severely restricts current from flowing in the opposite direction. Diodes are also known as rectifiers because they change alternating current (ac) into pulsating direct current (dc). Diodes are rated according to their type, voltage,…

What is a LED?

A light releasing diode is none other than an electric component that would emit light when the current of electricity would be passing through it. Light Emitting Diode Symbol The figure demonstrates the LED symbol: this would be somewhat similar to p-n junction diode where the only change would be that the two arrows would…

Transistors

In that article I focused on what are called passive circuits. Passive components include resistors, capacitors, inductors, transformers, etc. An active circuit on the other hand uses more complex components like transistors. An electronic component is considered active if it allows the device to control the current in other parts of the circuit. This article was originally published on…

Capacitor

Everything You Need to Know About How a Capacitor Works No, we’re not talking about Grand Theft Auto here! Popping a cap in the world of electronics is not good unless you like seeing your electrolytic capacitor burn up in flames. Capacitors play a significant role in the family of passive electronic components, and their…

Resistance

The electrical resistance of a circuit component or device is defined as the ratio of the voltage applied to the electric current which flows through it: If the resistance is constant over a considerable range of voltage, then Ohm’s law, I = V/R, can be used to predict the behavior of the material. Although the definition above involves DC…
