Explanation

A logic gate is a basic building block of a digital circuit that performs logical operations (AND, OR, NOT).

It processes binary inputs (0s and 1s) to produce a single binary output.

Explanation

The word "transistor" is derived from "transfer" and "resistor".

It signifies the transfer of resistance — specifically, it controls a large output resistance using a small input resistance.

In essence, a transistor transfers a signal from a low-resistance circuit to a high-resistance circuit, acting as an amplifier or switch.

Explanation

 A PN junction diode allows current to flow only in one direction — from P to N (forward bias).

During the positive half cycle of AC, the diode is forward-biased (low resistance), so current flows.

During the negative half cycle, the diode is reverse biased, so it blocks current and offers high resistance.

Explanation

A Circuitry is a path in an electronic circuit.  

In electronics, a circuit is a complete circular path that electricity flows through.

A simple circuit consists of a current source, conductors and a load.

Explanation

A diode characteristic curve is a plot between voltage and current.

It shows the relationship between the applied voltage across the diode and the resulting current.

It indicating the diode's behavior in both forward and reverse bias.

Explanation

Full wave rectification is given by four diodes connected in bridge type arrangement.

This configuration allows both halves of the A.C. waveform to be used, producing a smoother and more efficient output compared to half-wave rectification.
