## Passive elements – capacitance

Capacitance is an ideal element of an electric circuit, replacing the capacitor, storing the energy of electric field. Capacitance is marked with the letter…

## Replacing circuit components with ideal circuit elements

Let us talk about the importance of replacing real circuit components by their ideal circuit elements, taking into account complex factors. Representation of resistance,…

## Linear electric circuits

Linear electric circuits and linear circuit elements are those where resistance, capacitance and inductance are not dependent on the current or voltage magnitude and…

## Voltage and current division – equivalent resistance for series connection

Let us take two resistors R1 and R2 in series and voltage source V (Figure 8). Resistors are in series here and create a…

## Voltage and current division – equivalent resistance for parallel connection

Let us take n resistors R1 ... Rn connected in parallel with voltage source VS1. According to Ohm’s Law the same voltage corresponds to…

## Wye-Delta conversions

The connections considered in the previous article (8) are quite simple for calculation. However, usually electric circuit schemes appear complex where it’s not easy…

## Methods of analysis nodal / mesh

When designing a complex electrical device there are a lot of factors that occur, like current leaks, heat flow, electromagnetic fields, behaviour of electrical…

## Volt-ampere characteristics of a circuit part with source

Ohm’s Law can be applied to a piece of a circuit with a source, and we can draw a Volt-Ampere characteristic for this piece…

## Kirchhoff’s Law application for circuits analysis

Basic laws of electric circuit theory are Kirchhoff's Laws – the law of the currents balanced in the circuit nodes (first Kirchhof's Law) and…
