Resistors in series. Voltage divider circuit and equation
Resistance is an electric circuit component, which is characterised by energy losses in a circuit as heat, some mechanical work, or electromagnetic radiation. No…
Resistors in parallel. Current divider circuit and equation
Two or more resistors are said to be in parallel, if identical voltage is across all the resistors. In accordance to Kirhhoff's Law the…
Passive elements – inductance
Inductance is an ideal electric circuit component which is close to the inductor in its features and components - collecting the energy of magnetic…
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 C…
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 division – equivalent resistance for series connection
Let us take two resistors R1 and R2 in series and voltage source V (figure below). Resistors are in series here and create a single-loop with…
