Ohm’s Law is a fundamental principle in physics and electrical engineering. It describes the relationship between

Ohmic resistors are fundamental components in electrical engineering. They are present in every circuit, so the

LEDs require a current-limiting resistor to operate at the ideal operating point and ensure a long

A current divider is a parallel connection of resistors. The same voltage is applied across all

A voltage divider is a linear circuit with two resistors, where the input voltage divides into

When connecting two or more resistors in series, the same current flows through all resistors. But

When connecting two or more resistors in parallel, the current is divided at the junction point

The internal resistance of a voltage source is an important parameter in electrical engineering. The internal

A smoothing capacitor reduces the residual ripple of a previously rectified voltage. This article describes the

The cross-section of a cable wire should be selected to match the current consumption of the

The LC filter, also called the LC filtering element, designates a circuit with an inductance L

This site explains the exact operation of an RC filter and its individual components. Below we

A low pass filter only passes signals below its cutoff frequency and weakens the components above

A high pass filter prevents frequencies below its cut-off frequency from passing and lets through signals

A band pass filter lets only a certain frequency band pass through and attenuates frequencies below

A band stop filter filters a defined frequency band out of the signal. The terms “band
