Current Law Details

The electric current in amperes that flows into any junction in an electric circuit is equal to the current which flows out. This can be seen to be just a statement of conservation of charge. Since you do not lose any charge during the flow process around the circuit, the ...

Voltage Law Details

The voltage changes around any closed loop must sum to zero. No matter what path you take through an electric circuit, if you return to your starting point you must measure the same voltage, constraining the net change around the loop to be zero. Since voltage is electric potential energy ...

Ohm’s Law Details

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points. Introducing the constant of proportionality, the resistance, one arrives at the usual mathematical equation that describes this relationship: where I is the current through the conductor in units of ...

Basic Electrical Circuit Theorems for Circuit

Basic Electrical Circuit Theorems: To solve problems in electrical networks, there are number circuit theorems have been developed like (1) Kirchhoff's laws (2) Superposition theorem (3) Thevenin theorem (4) Norton Theorem (5) The maximum power transfer theorem In this post we have listed all these theorems. We believe that this post will serve as a ready reference ...

Basic Electrical Engineering Interview Questions

What is Current? Current can be defined as the motion of charge through a conducting material. The unit of current is Ampere whilst charge is measured in Coulombs. Please define Ampere:- The quantity of total charge that passes through an arbitrary cross section of a conduct-ing material per unit second is defined as ...

SYSTEMS OF UNITS

In the past, the systems of units most commonly used were the Englishand metric, as outlined in Table . Note that while the English system is based on a single standard, the metric is subdivided into two interrelated standards: the MKS and the CGS. Fundamental quantities of these systems are ...

Counter (digital)

In digital logic and computing, a counter is a device which stores (and sometimes displays) the number of times a particular event or process has occurred, often in relationship to a clock signal. The most common type is a sequential digital logic circuit with an input line called the 'clock' ...
