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 ...

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 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:
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 ...

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 ...

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 ...

What is an Address in Communication Systems?
It should be called as designator for the location of data in a storage device; allows the retrieval of data by reading the contents of a specific location. Also, the identity of a peripheral device. These (normally unique) allow individual devices on a ...

What is AC voltage controller?
It is defined as the power electronics converter which converts the fixed AC voltage into a variable AC voltage without change in the frequency.
What is inverter? What are the types of Inverter?
A device which converts dc power into ac power at desired output voltage ...

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' ...
