To measure inductance with an oscilloscope, you can use three frequent methods. The first one is the resonant frequency method, the second one involves using a resistor of known value and the third one is by using voltage-current slope. Inductances…
To determine the threshold voltage, use the equation of the drain current as a function of the gate to source voltage VGS in the VDS saturation region. VDS(sat)=> VGS-Vth defines the saturation region. The transfer curve at drain current saturation…
MOSFETs (Metal Oxide Semiconductor Field Effect Transistor) are of four different types or modes. They may be enhancement or depletion mode or maybe N channel or P channel. How does a MOSFET work? Here we provide a Java applet tutorial of N…
The fuse goes on the positive wire of a DC system and the phase wire of an AC system. Putting the fuse wire on the positive and phase wires for the DC and AC systems respectively protects the load and…
Yes, you can use a 7.5 capacitor in place of a 5. But in most cases, it is determined by other capacitor specifications, such as voltage, as well as the application. When capacitance increases in a capacitive circuit, the capacitive…
Op-amp and transistor are used according to your need. Though op-amp is better for amplifying gain, they are expensive. As the op-amp amplifier is made of different types of transistors. So, in many cases, you can use a transistor instead…
Yamaha receivers allow you to control audio over many speakers by utilizing channel audio options. They also boost that sound, and even do single-room correction on the signal, all of which increase sound quality. A problem in your Yamaha receiver…
While BJT shines in low frequency, MOSFET works best in high-frequency amplifiers. A transistor and a MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) both have their benefits and are appropriate for different applications. For an amplifier, the use of BJT and MOSFET depends…
With some easy steps, you can test a Triac using a digital multimeter or an ohmmeter. While using a multimeter, a digital multimeter is suggested for this test as these kinds of multimeters show more accurate readings than analog ones….
