Mesh analysis in a resistor network – Mesh current method in a resistor network.
Mesh current analysis or the mesh current method is a technique used to find the currents circulating around a mesh with in any closed path of a circuit.
Resistors in series and parallel How to obtain the equivalent resistor value of resistors in series and parallel. Resistors in series To implement a circuit with resistors in series you have to connect one resistor after the other one. (see the image). The equivalent resistor value of the resistors connected in series is equal to the […]
Logic AND gate The logic AND gate is one of the simplest gates in Digital Electronics. The symbols for a 2 and a 3 input AND gates are shown in the following image. The first one is the symbol of a 2-input AND gate and the second one is the symbol of a 3-input AND gate. 2-input and […]
RC Low Pass Filter An RC low pass filter is a circuit made by a resistor and a capacitor connected in series, as shown in the image below. The RC low pass filter allows only the passage of frequencies below a particular frequency called cut-off frequency (Fc) and eliminates frequencies above this frequency. These RC […]
Series and Parallel Inductors – Series & Parallel equivalent inductance.
On many occasions it is necessary to obtain the equivalent value of a set of inductors that are connected in series or parallel. This are the simplest methods to calculate the values (inductance) of series and parallel inductors.
