Electrical Circuit Analysis

The electrical circuit analysis is a set of techniques used for quantitative analysis of a circuit.

The circuit analysis helps the engineers to find out the behavior of each element in the circuit before physically connecting it. Using pen and paper for electrical circuit drawing and calculation, can save a lot of money and avoid a hazardous situation like a short circuit and component lose.

Difference between ideal and practical/Voltage and Current Source

Difference between ideal and practical Source

In contrast to a practical voltage source, an imaginary deal source provide constant voltage regardless of load current because of no internal resistance. While ideal current source provides a constant current regardless of load current.

Maximum Power Transfer Theorem Proof and Example

Maximum Power Transfer Theorem

Maximum Power Transfer Theorem state that maximum power will transfer from source to load if and only if the load resistance is equal to source internal resistance. The theorem is purely about the transfer of power not efficiency.

Thevenin Theorem: The Thevenin Equivalent Circuit

Thevenin Theorem The thevenin equivalent circuit

According to Thevenin Theorem, a complex circuit is reduced to two resistor network, Thevenin Resistor, and Load resistor and a Thevenin Voltage source to avoid redundant computation to analyze a frequent changing resistor.

Resistors in Parallel Circuits: Equivalent Resistance Calculator

Resistors in parallel circuit

Resistors are said to be parallel if there is only one path for the flow of current. The total resistance in parallel is less than the individual resistors in parallel.

Resistors in Series Circuits: Equivalent Resistance

Resistors in series circuit

Resistors are in series if there is only one path for the flow of current. That's why current remain same for all the resistors in series.
