WHAT IS ELECTROPLATING AND POLARIZATION

Electroplating: Electroplating uses the principle of electrolysis to apply a thin coat of one metal to another metal. Some practical applications include the tinplating of steel, silver-plating of nickel alloys and chromium-plating of steel. If two copper electrodes connected to a battery are placed in a beaker containing copper sulphate...

DEFINE MAGNETIC FLUX AND MAGNETIC FLUX DENSITY

Magnetic flux: Magnetic flux is the amount of magnetic field (or the number of lines of force) produced by a magnetic source. The symbol for magnetic flux is  Φ (Greek letter ‘phi’). The unit of magnetic flux is the weber, Wb. Magnetic Flux density: Magnetic flux density is the amount of flux passing through a defined(specific)...

DEFINE CONDUCTORS,INSULATORS AND SEMI-CONDUCTORS

Some materials allow electric current to flow more freely than others. These materials are called conductors. Other materials are resistant to the flow of electric current. These materials are called insulators. Conductors and insulators are both important in the field of electronics.  Conductors: Conductors allow electric current...

DEFINE OHMS LAW

One of the most important and basic laws of electrical circuits is Ohm's law which states that the current passing through a conductor is proportional to the voltage over the resistance.  Equation Of Ohms Law: Ohm's law may sound a bit confusing when written in words, but it can be described by the simple formula: I=V/R where I =...

DEFINE RESISTORS,CAPACITORS & INDUCTORS

The three basic elements used in electronic circuits are the resistor, capacitor, and inductor. They each play an important role in how an electronic circuit behaves. They also have their own standard symbols and units of measurement.  Resistors: A resistor represents a given amount of resistance in a circuit. Resistance is a measure...

DEFINE CIRCUIT LOADS

Circuit Loads: A load generally refers to a component or a piece of equipment connected to the output of an electric circuit. In its fundamental form, the load is represented by any one or a combination of the following: 1.Resistor(R) 2.Inductor(L) 3.Capacitor(C) A load can either be of resistive, inductive or capacitive nature or a...

DEFINE VOLTAGE

Voltage or potential difference between two points in an electric circuit is 1V if 1J (Joule) of energy is expended in transferring 1C of charge between those points. It is generally represented by the symbol same letter, however, it rarely causes any confusion.V and measured in volts (V). Note that the the unit of voltage are both denoted...
