Electric shocks provide electrical and electronics engineering web-based calculator for different formulas from the field. Electrical Engineering deals with different formulas that can be calculated with on web calculator.
Resistor color coding is the system for representing the rating of the component by marking different color bands over the packing. It is also used for capacitor, inductor, and diode but most commonly for resistors.
Star Delta Transformations and Delta Star Transformations allow us to convert resistances or impedances connected together at three different nodes from one type of connection to another and vice versa.
