Wirewound Resistor

A wirewound resistor is used when the power to be dissipated is very high. A wire wound resistor is usually coated with a layer of vitreous enamel.

Light detector circuit using LDR (automatic night light)

This circuit activates a lighting device through a relay when the intensity of daylight is no longer sufficient. Good for illuminating the main entrance of the house, a display case that needs to be kept lit at night, an unsafe area at night, etc.

Logic Probe using NOT Gates

A very simple logic probe using NOT gates. The logic probe allows us to know the logic state of any point in a digital circuit. The signal to be measured is applied to the probe tip input.

Node Analysis Method – Steps – Example

The node analysis method also known as the nodal analysis is widely used to solve linear resistive circuits (this method, in a slightly extended form, also applies to resistive-reactive circuits)
