What is a standalone power generator ?
A standalone power generator, often referred to simply as a generator, is a device designed to convert mechanical energy into electrical energy independently of an external power source. This type…
What does a solid state radar mean ?
A solid-state radar refers to a type of radar system that utilizes solid-state electronic components, such as gallium nitride (GaN) or gallium arsenide (GaAs) semiconductor materials, in its transmitter and…
How does the resonant frequency affect the voltage drop across a resistor?
How does the resonant frequency affect the voltage drop across a resistor? For all intents and purposes, a resistor has no resonance frequency. its parasitic capacity is considered insignificant. if…
What are the failures of Ohms law ?
Ohm’s Law, which states that the current through a conductor between two points is directly proportional to the voltage across the two points, provided the temperature remains constant, is a…
Why magnetizing current is non sinusoidal in transformer ?
The magnetizing current in a transformer is non-sinusoidal due to the inherent characteristics of the transformer core and the way it responds to the alternating magnetic field generated by the…
What does recovery mode mean on a thermostat?
The recovery mode is when the thermostat prematurely turns on the heating / cooling so that it reaches the set point at the scheduled time. In other words, you set…
Why does a DC motor draw a high inrush current when starting ?
When a DC motor starts, it experiences a phenomenon known as inrush current, where the current drawn by the motor momentarily spikes to a high level. This high inrush current…
A diode is called a rectifier Why ?
Diodes as Rectifiers: 1. Introduction to Diodes: Semiconductor Devices: Diodes are semiconductor devices with two terminals, known as the anode and cathode. They allow current to flow in one direction…
Why is possible to change instantaneously voltage across a resistor?
Why is possible to change instantaneously voltage across a resistor? The capacitor and inductor do not allow sudden changes in voltage or current. This is because both devices build up…
What is the difference between a transistor and a variable resistor?
What is the difference between a transistor and a variable resistor? A resistor is considered a passive device and has two connections and a nominal fixed resistor. A transistor is…
