How to convert 230V AC TO 12V DC ?
Converting 230V AC to 12V DC involves using a power supply or a transformer along with a rectification and smoothing process. Here’s a detailed explanation of the steps involved: 1….
Why do old vacuum tube amplifiers sound so rich compared to modern Transistor FET amplifiers?
There are mutliple reasons for this: Tube amplifiers produce more even harmonics than solid state amplifiers. Solid state amplifiers, on the other hand, are rich in odd order harmonics. For some evolutionary…
What is rectifier circuit?
A rectifier is an electrical device that consists of one or more diodes and converts alternating current (AC) to direct current (DC). A diode is like a one-way valve, in which electrical…
How to test a thyristor?
How to test a thyristor (SCR): Obtain a bench DC power supply with adjustable output voltage and current limit. For example 0–30Vdc 0–5A Set the power supply to around 30 Vdc…
How to select the capacitor voltage ?
Selecting the appropriate capacitor voltage rating is crucial to ensure the reliable and safe operation of electronic circuits. The voltage rating of a capacitor indicates the maximum voltage the capacitor…
How to tune an RC transmitter ?
Tuning an RC (radio control) transmitter is a crucial step to ensure optimal performance and responsiveness of your remote-controlled model. Here is a detailed guide on how to tune an…
How to convert current into voltage ?
Converting current into voltage involves the use of a device called a resistor. This process is governed by Ohm’s Law, which states that the voltage across a resistor is directly…
When does the open resistor read an infinite value in an ohmmeter?
When does the open resistor read an infinite value in an ohmmeter? If the resistor is really open, it will measure infinity when you check it with an ohmmeter. in…
Why the voltmeter needs to be connected in parallel with resistor?
Why the voltmeter needs to be connected in parallel with resistor? Because a voltmeter measures a potential difference, voltage. It compares the voltage on one probe with the voltage on…
