## What is Transducer? – Working, Types and it’s Application

A transducer is a device that converts any physical quantities into a proportional electrical signal (voltage and current). In general words, the transducer is a device that converts one form of energy into another which is measurable in the form of an electrical signal. That process of converting energy from one form to another form is known as Transduction.

## Nilpotent Matrix – Definition, Properties and Example

Any square matrix [A] is said to be a Nilpotent matrix if it satisfies the condition [Ak] = 0 and [Ak-1] ≠ 0 for some positive integer value of k. Then the least value of such positive integer k is called the index (or degree) of nilpotency.

## Core Balance Current Transformer (CBCT) or Zero Sequence CT (ZCT)

A core balance current transformer (also termed as CBCT) is a ring-type current transformer (CT) through the center of which either three single-core cables or a single three-core cable of three-phase system passes. That three-core cable forms the primary winding of CBCT.

## Idempotent Matrix – Definition, Examples and its Properties

Mathematically we can define an Idempotent matrix as A square matrix [A] will be called an Idempotent matrix if and only if it satisfies the condition  A2 = A. Where A is n x n square matrix.
