How does a spark plug produce current ? A spark plug produces current through a process involving an electrical discharge that jumps across a gap between two electrodes inside the combustion chamber of an engine. When the ignition coil generates a high-voltage pulse, typically from 12,000 to 45,000 volts depending on the engine, this voltage … Read more
What is the SI unit of entropy ? The SI unit of entropy is joules per kelvin (J/K). Entropy is a thermodynamic quantity that measures the amount of disorder or randomness in a system. In SI units, entropy is expressed as energy per unit temperature, where joules (J) is the unit of energy and kelvin … Read more
What is a crystal? A crystal is a solid material whose atoms or molecules are arranged in a highly ordered repeating pattern, extending in three dimensions. This atomic arrangement results in a regular, geometrically shaped structure that gives crystals their characteristic properties, such as clarity, hardness, and often a symmetrical external form. Crystals can form … Read more
Which motor should be best for line follower robot for fast speed ? Selecting the best motor for a line follower robot intended for fast speed depends on several factors such as the weight of the robot, the type of surface it will traverse, and the desired speed. In general, DC motors with high RPM … Read more
How are cathode rays produced ? Cathode rays are produced through a process involving the application of high voltage to electrodes in a vacuum tube. Specifically, a cathode ray tube (CRT) begins the production of cathode rays with the emission of electrons from a heated cathode. When the cathode is heated, it releases electrons due … Read more
How are you meant to know how much power supply any circuits require ? Determining how much power supply a circuit requires involves several considerations. First, you need to assess the power consumption of each component in the circuit. This includes identifying the voltage and current requirements of resistors, capacitors, integrated circuits, and any other … Read more
A diode curve tracer is an instrument used to graphically display the electrical characteristics of diodes, typically showing the relationship between voltage (V) applied across the diode and current (I) flowing through it. It allows engineers and technicians to visualize the diode’s behavior under different operating conditions, such as forward bias and reverse bias. By … Read more
How to calculate the fuel consumption of the generator ? Calculating the fuel consumption of a generator involves several factors that influence its efficiency and power output. To determine fuel consumption, you typically need to know the generator’s rated power output in kilowatts (kW) or kilovolt-amperes (kVA), as well as the specific fuel consumption rate … Read more
What is the firing angle of a thyristor ? The firing angle of a thyristor refers to the delay in degrees or radians between the instant the thyristor begins to conduct current after a gate signal is applied and the point in the AC waveform where the voltage across the thyristor becomes positive enough to … Read more
Relays are electromechanical switches that operate based on the principle of electromagnetic induction. They typically have a specified operating voltage range within which they can reliably function. If you attempt to operate a 5V relay with 12V, it may lead to several issues. Firstly, the coil of the relay is designed to operate at 5V, … Read more
