The opposition to flow of electrons (due to bonds between protons and electrons, as well as to collisions) is called a electrical resistance (R). Or Resistance may also be defined as “The property of the electric circuit which opposes the flow of current”. The practical unit of electric resistance is …

Kirchhoff’s Voltage Law states that net voltage gain and net voltage drops along a closed loop are equal. Kirchhoff’s Current Law states that at any point in the circuit the total current enters, is exactly equal to the total current leaves the point. There are some simple relationships between currents and voltages …

There are many names in the field of atomic model and atomic structure. The first name to understand the atomic structure of matter was J.J.Thomson who represented the Plum Pudding Model, that was based upon the concept that electrons in an atom are distributed on positive charge just like plums in a …

In Coriolis effect a mass moving in a rotating system experiences a force (Coriolis force) acting perpendicular to the direction of motion and to the axis of rotation. On the earth, the effect tends to deflect moving objects to the right in the northern hemisphere and to the left in …

Read More »## What is Doppler Effect Definition Equation and Formula? [Answered]

Definition of Doppler Effect Doppler effect is the change in frequency of a wave for an observer moving relative to its source. The observer observes an upward shift in frequency when the wave source is approaching, and a downward shift in frequency when the wave source is retreating. In other words, …
