PM Modulated Radio and FM Signal: A radio receiver designed to demodulate PM (Phase Modulation) signals typically cannot directly receive and demodulate FM (Frequency Modulation) signals. PM and FM are different modulation techniques where PM varies the phase of the carrier signal in response to the modulating signal, while FM varies the frequency of the … Read more
There are claims about fake and real free energy generators, but it is important to approach these claims with skepticism. The concept of a free energy generator often refers to a device that can produce more energy than it consumes, seemingly violating the law of conservation of energy. Many purported free energy devices have been … Read more
In a domestic circuit, a fuse is typically connected in series with the live wire (also known as the hot wire) of the electrical circuit. This placement ensures that all current flowing through the circuit must pass through the fuse. The fuse itself is housed in a fuse holder, which is connected to the live … Read more
Electric motors produce mechanical energy through the interaction of magnetic fields. When an electric current flows through a wire coil inside the motor, it creates a magnetic field around the coil according to Ampère’s law. This coil is placed in a magnetic field produced by permanent magnets or electromagnets. The interaction between the magnetic fields … Read more
LEDs (Light Emitting Diodes) are semiconductor devices that emit light when current flows through them in the forward direction. When connected correctly in a circuit with the anode (+) connected to the positive voltage and the cathode (-) to the negative voltage (assuming it’s a DC circuit), LEDs illuminate as electrons recombine with electron holes … Read more
A 3-phase induction motor cannot run directly on a single-phase line without modifications. These motors are designed to operate with three-phase power, which provides a balanced power supply and efficient operation. However, with certain techniques such as using a phase converter or capacitors, it is possible to run a 3-phase motor on a single-phase supply, … Read more
A transistor and an operational amplifier (op-amp) are fundamentally different electronic components with distinct functions and characteristics. A transistor is a semiconductor device used primarily for amplification or switching electronic signals. It has three terminals: emitter, base, and collector. Transistors can amplify current or voltage signals based on the configuration (common emitter, common collector, or … Read more
Transistors, while highly versatile and fundamental in modern electronics, have several limitations. One significant limitation is their maximum power handling capability. Transistors can only handle a limited amount of power before they may overheat or suffer damage. This limits their use in high-power applications such as power amplifiers or motor control circuits, where higher currents … Read more
What should be ground to neutral voltage ? The ground to neutral voltage in an electrical system ideally should be zero volts. This means there should be no potential difference between the neutral conductor and the grounding system. In a properly functioning electrical installation, the neutral conductor and the grounding conductor (earth) are bonded together … Read more
Yes, there are alternatives to the Big Bang theory. One such alternative is the Steady State theory, which suggests that the universe has no beginning or end and is always expanding, with new matter continuously created to maintain a constant density. Another alternative is the Cyclic model, which proposes that the universe undergoes infinite cycles … Read more
