Difference between Galvanic Cell and Electrolytic Cell

A galvanic cell is the one in which an oxidation-reduction chemical reaction occurs spontaneously to generate electrical energy. Chemical energy is converted into electrical energy. An electrolytic cell is the one in which electrolysis process takes place, a chemical compound is disintegrated by passing electricity through it. The chemical reaction …

Physical Quantities and Units | Systems of Units

Physical quantities are values determined by making measurements or obtained by being calculated from other measurements.  An example of obtaining a value from a measurement is using an odometer or another measurement device to determine the distance a car travels or using a watch to determine how much time it …

Simple Harmonic Motion and Uniform Circular Motion

Period and Frequency in Oscillations                When a guitar string is plucked or a spring moves up and down, the time interval between each oscillation is defined as periodic motion. The time that one oscillation is completed is called the period. In addition to indicating repeated oscillations, a period can …

Push Button Switch Types and Circuit Diagram

Industrial Push Buttons Push buttons, shown in figure 1, are the most common type of control devices found in industrial facilities. Almost all industrial machines contain push buttons even if the facilities operation is to set to run automatically. Typical push buttons are momentary meaning they are designed with a …

What is Hooke’s Law | Definition Formula

Hooke’s Law Introduction There are many examples of things that oscillate. Oscillations refer to an object or system that moves back and forth between two points and creates waves.  A guitar string vibrates back and forth when plucked; the oscillations of the cone inside an audio speaker makes it produce …

Difference between Electric field and Magnetic Field

An Electric field takes place where a voltage exists. They are produced around appliances and cables since a voltage exists. If the voltage is higher, an electric field is stronger and its strength is measured in volts per meter (V/m). The field strength diminishes quickly as we move away from …

Difference between DC Motor and DC Generator

DC motor and DC generator are similar from the mechanical perspective, however from a technical stand point, both differ from each other significantly. The most significant difference between DC motor and DC generator lies in the conversion mechanism. DC motor converts electrical energy into mechanical energy whereas DC generator converts …

Effect of Zeros on System Response

The zeros zj of G(s) do not affect the system stability. However, they do affect the amplitudes of the mode functions in the system response and can block the transmission of certain input signals. In general, to assess the Impact of the zeros on the amplitude of the mode functions, …
