The resolving power can be defined as the inverse of angular separation or distance, between the objects, and that can be resolved when viewing through the optical instrument. In the sky, some of the binary stars appear as one star, when they are viewed by the naked eye, but by using the optical instruments, their … Read more
A generator is mechanical equipment whose main work is to convert the mechanical form of energy into electrical energy and it also finds application in agriculture and industrial production and somehow production of a generator is highly based on the law of electromagnetic force. On the contrary, the transformer is passive to pass electricity between … Read more
When direct current is considered the voltage and current are constant and there is no problem in specifying their magnitude but when an alternating current is considered both alternating voltage and current varies from instant to instant and that possess problem how to specify the magnitude of the voltage and current. Voltage and current can … Read more
Power of AC circuit is a two-phase electric current which is mainly used in big industries which includes heavy machinery. The power of the three-phase AC circuit is three times powerful than the single-phase circuit. It is stated that electric power which is consumed by resistance in an AC circuit is different from the power … Read more
Literally resonance means the phenomena of amplification that could be occurred when the frequency of an applied force in a harmonic proportion to the natural frequency on which it acts and the oscillation acts at the higher level or amplitude then the same force is applied at the other. Resonant frequency or resonance frequencies are … Read more
Reactance and impedance are different from each other as reactance refers to electrical resistance in which the opposition to the change in voltage which may be happening due to the capacitance or maybe in current due to inductive reactance in which the imaginary component of AC impedance. It also consists of magnetic reactance which is … Read more
What is the literal meaning of oscillation is the first question arises and answer to this is oscillation or oscillators are electronic circuits that generate a continue periodic waveform at a precise frequency another explanation is that oscillation can convert a DC into an AC output or can be called waveform which can have a … Read more
It is an electrical circuit consisting of an inductor that stands for L, capacitor which stands for C and resistor which stands for R which are connected in series or parallel. This name LCR is derived from the sequence of these letters used to denote the constituent components of this circuit. This circuit forms a … Read more
Wattless current is a current which is mainly referred to as an AC current which contains only capacitor or inductor having zero power dissipation even though the current is flowing through it. In other words when current is flowing and there is no loss of power and when a pure inductor or pure capacitor … Read more
Total Internal Reflection of Light and its Applications Total internal reflection is referred to as the complete reflection of light rays within the given medium from the surrounding surface. Generally, the total internal reflection takes place at the boundary between two transparent mediums when the light ray in the medium of high refractive index is … Read more
