Bandwidth and sample rate are the two most important features of an oscilloscope. Bandwidth is the frequency range that an oscilloscope can accurately measure. And sample rate is the number of data readings that an oscilloscope takes per second. Bandwidth…
Use diode 1N5400 or 1N5402 up to 1N4008 for 12V. All these diodes are rated for a 3 Amp rating. Diodes for such currents can have a significant voltage drop. The voltage drop in a tiny silicon diode working at…
The initial voltage across the capacitor is zero after switch s1 is closed. Before the switch closes, the capacitor’s charge Q is zero and its voltage across the capacitor is equal to zero (V = Q/C = 0). The capacitor’s…
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…
370 and 440 capacitors simply mean 370 VAC and 440 VAC capacitors. These two capacitors are most commonly used as run capacitors of an AC induction motor. Between 370 VAC and 440 VAC capacitors, it is always preferable to use…
Film capacitors are used more than ceramic Capacitors. Film capacitors are suitable for a wide range of capacitance values whereas ceramic capacitors are suitable for a range of capacitance. Definition and Types of Capacitors Capacitors are electrical devices used to…
Both analog and digital oscilloscopes are used for the same work. But there are some extra features in a digital oscilloscope. The oscilloscope is an electronic measurement instrument. It is also known as an oscillograph, scope, CRO (cathode ray oscilloscope),…
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…
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…
