RC discharging circuits use what is called the RC time constant which is an inherent property exhibited by an resistor-capacitor combination. This time constant determines how fast the capacitor discharges and it does so in an exponential way, meaning the voltage does not just drop steadily; it decreases more and more quickly as time gradually […]

Pull-up Resistors and Pull-down Resistors: How to Calculate
In my practical works, when connecting digital logic gates to external circuits or devices, I personally ensure that their inputs and outputs are properly set to provide the correct switching conditions. This is where Pull-up Resistors come into play, because they help make sure that the inputs or outputs are functioning as per the expectations. […]
How to Calculate Star Delta Transformation
With methods like Kirchhoff’s Law, Mesh Current Analysis, and Nodal Voltage Analysis, we’ ve already mastered fundamental circuit analysis and can easily address problems with simple resistive networks. But how about complex three phase circuits? This is where the Star- Delta Transformation becomes so useful. This effective method greatly reduces the mathematical complexity of balanced […]
How to Calculate Mesh Current in a Circuit
Mesh current analysis calculates currents in closed loops of a circuit by assigning hypothetical loop currents and using Kirchhoff’s Voltage Law. Although the basis for evaluating any electrical circuit is provided by Kirchhoffs Current Law (KCL) and Voltage Law (KVL), other methods such as Mesh Current Analysis and Nodal Voltage Analysis are also available. These […]
